I have just broken down, TC light came on with electronics light, starts but misfiring like hell, can't drive off.
any ideas, had a new water pump fitted yesterday.
help
-
Pedal test?
-
can you do the pedal trick for codes?
-
been trying, can't remember howto do it
-
Foot on brake, gas pedal to the floor.
Turn on ignition to position II (do not fire the engine in position III)
When dash lights go out the yellow light car symbol with a spanner through it should flash.
4 sets of flashes/numbers pause and so on.
10 flashes is zero.
Constant flashing no codes.

cheers, reads 10 1 1 10

P0110 Intake Air Temperature Circuit High Input
P0110 Intake Air Temperature Circuit Low Input
wiggle all the connectors near the airbox?
-
It's a facelift so doesn't have the seperate air temp sensor. Try unplugging the MAF as air temp is calculated from there on the later cars. Should run a default program then.
Not sure why the TC lamp should be lit though.
-
ahhh yes, didnt you have a load of MAF grief around the york meet time?
-
tried wiggling a few things and unplugged maf, no change.
-
got breakdown cover?
-
presume your coolant level is ok?
-
coolant ok
-
Shot in the dark but is it worth checking any connectors around the waterpump area?
I was thinking the connector under the DBW throttle and the Knock sensor connector that exits the trunking on the lh side of the engine.

Given the water pump change: might the cam-belt be implicated here? (tension/timing-registration/slipped).....whilst I hope not, it is just a thought.
-
on way home in recovery.
-
Least you can have a propper look at home.
have you got any other diag equipment than the pedal test?
-
Right back home, just found out i the brake pedal is solid with engine on, so no brakes. I'm at the limit of my knowledge now, tried what everyone said. got a m8 who thinks he can get a diagnostics thing but he said its snapon not tech 2!! don't know what that means. waiting for him to get back to me now!!
-
does sound a bizarre set of issues.
if this diag kit can do live data from various ecu's, with a bit of luck should help pin it down.
-
The guy on the phone sounded baffled too. Just gotta wait now. I hate waiting.
Don't look like i'm off to work today!! :'( :'(
-
If the brake servo is not working then it must be a leak in the vacuum system, and by the sounds of it a big one.
-
when did y9ou last fill up with petrol?
not just put in a different talkful to normal?
-
Check the breather connection along to the master cylinder from the manifold
-
put £30 in on friday from empty. All my problems started on friday when i was low on fuel and parked on a steep driveway, started the car and cut out so rolled off onto flat and started, immediatly the water pump started knocking so had that changed yesterday, all ok till this morning about 1mile from this al happens.
Wether its all related i aint a clue! :'(
-
Hmmmm....water pump change.....is the brake servo pipe attached and all ok. Check also the wires around this area
Plenum has to come off on the DBW units to get the cambelt cover off to change the water pump.
So my money is on the garage having balls'd it up!

may be worth thinking about a new fuel filter as well next service.

Hello,
May be a shot in the dark.
My old 2.5 started to misfire, would not run properly and no servo-sounded a bit like yours. A large push in pipe that goes into side of the plenum on the top of the engine passenger (it's pushed in one end and connected to a metal cylinder and additional pipes the other end)side had popped off slightly-difficult to see- and so was sucking in air. Pushed it back in end of problem until it did it again. ended up ziptying it on.
Regards
Steve
-
Everything looks ok to me but I don't know what half the stuff i'm looking at is!!
markey mark the gent that he is, is gonna come over in the morning to have a look for me!! fingers crossed its summat & nowt

Thats the brake servo pipe as mentioned above :y
-
Looks like its fixed, for now. The mechanic I know has been round to look at it for me while I'm at work!! I don't know the full details yet but it was only firing on 1 bank, and it looks like it was to do with the throttle motor sticking or summat. He said all is fine now. Will get more details when I finish work. :y

What a load of cobblers!

I might of miss-understood over the phone so I will confirm when I speak to him tonight.
I take it that doesn't sound plausible then :-?

Lol, if it was then the main throttle shaft has snapped!
My money is still on a major air leak......and will most likely be related to the work recently done (to much of a coincidence!)

as a general rule, for here, for every visit you need another visit to repair a car thats already repaired ..
so you need to visit mechanics endlessly and become good friends ;D ;D :y
look in the bright side after they start to do it free as they are ashamed ;D
-
I would be taking it back to whoever 'fixed' the water pump and get them to put it right.... ::) ::) ::)
-
They did fix it today. It was P1500 when it went on the diagnostics. It has been cleaned up and now seems fine, nothing to say it won't fail again but now know how to check it and sort it out if it happens again. I don't think the water pump fitting will have had anything to do with this.
-
Well P1500 relates to an electronic throttle control failure which could be linked to the water pump change as this has to be disconnected to remove the plenum.
And if it was this then it would not run at all
-
The only thing is the car ran fine for a while after the waterpump was fitted,
Started the car this morning and it was a bit jittery to start with and then ok, feels like the throttle body motor is not happy.
I have been having this jittery thing since I put the new MAF on and assumed it was the MAF causing it but now I am starting the think it was the throttle body all along and its just been developing. Only a guess though.

And, if they have not correctly re-fitted something (i.e. the electronic throttle control connector) then after a period of time, it will start to play up.
The poor idle on startup could be an air leak......it could be a poorly MAF!

They do run - just like a bag of shit, won't idle won't rev
WD 40 fixed mine - rain water in the wiring

Just thought i'd post an update, markey mark cleaned the throttle body at the weekend and it has fixed the problem I was getting on cold starts in a morning which I thought was being cause by the new MAF I put on (as the problem started immediatly after installing the MAF)
Anyway I am well chuffed its all back to normal.
Fingers crossed the throttle motor is ok and it was just grime & dirt that caused the breakdown the other day!! :y
-
Ok bit disapointed this morning. The mig ran perfect for 2 days and this morning it was lumpy and unresponsive again for about 30 seconds then was fine. Just like it was doing before. :'(
I don't want to leave it again in case I get a repeat breakdown, so I am now officially on the lookout for a throttle body to test/borrow/buy. anything to prove it is the throttle body causing it to be like this in a morning. Think markey mark has a "known good" MAF that I can borrow just to rule that out too.
Any help/advice on this will be much appreciated. :y
-
:'( OK just another update, I have tried another Complete throttle body (used) and the car has done exactly the same thing this morning, doesn't want to rev, lumpy, backfiring etc, same as before. So I can rule out the Throttle Body. Still waiting for another MAF to try but can anyone think of anything else that could be causing this.
I really need to get it right for the weekend, driving to leicester and I really need the car to 100%.
Help!
-
:'( :'( :'(
frustrating when you cant pinpoint it >:(
-
Your not kidding, I am really desperate now! Getting on my nervs. lol. Looking all over the web for the best price on a Genuine MAF, £115 so far, but I don't want to spend £115 if i don't know if thats the problem.
Same with the throttle body, I'd of been gutted if i'd spent the £260 on an new one only to find out that wan't the problem.
:'( :'( :'(
-
aye, youve been battling this since before the York meet as well havent you?
-
Yep, getting old now isn't it! hehe.
Bet everyone sick of me banging on about it!! ;D

No, would rather it was fixed fast for you obviously....but threads should always reach a conclusion for future reference :y
-
I will be over the moon when this is fixed, can get back to normal then!!
I've posted in the wanted section now, see if anyone can help with a MAF locally. downside is there aren't many members nearby. :'(

A 2.6/3.2 MAF details are as follows:
Vx part number - 93171760
Bosch part number - 0281 002 184
I have used a few of these in the past with no problems
http://cgi.ebay.co.uk/NEW-Air-flow-mass-sensor-Meter-VAUXHALL-0281-002-184_W0QQitemZ230358716357QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item35a2730fc5&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A4%7C39%3A1%7C72%3A1683%7C293%3A1%7C294%3A200

The one on it at the moment is an ebay one, and the problems started when this was fitted, thats why I was after a genuine one.
Can anyone give me the probability of the MAF being tha cause of these problems? can the MAF actually cause the problems I have had etc?
I know its difficult to be confident, but you guys know allot more than I do. :y

A very important point Jb :y :y

When all is said and done, this car would benefit from a drive to Nottingham methinks.
-
The really tricky thing with this is the car only plays up in a morning, its fine after work after being stood 7 1/2 hours etc, only plays up after stood all night so its difficult to show people what its doing etc. :'(
-
Same symptoms as I had with Mick Dundees......and that was fixed with a new MAF

That makes me feel a bit better about buying a new MAF but its still a risk i suspect. Autovaux have a genuine one for £107 (£107 I can't really afford either) and they only in Wakefield so I could pick it up today.
I think I would definatly shed a tear in the morning if it doesn't fix it though. :'(
Plan at the moment is to look round some scrappers this aft but there aint that many around anymore. :-/

Mate
Please listen to Mark he is trying to save you £80.
I had one of those he has told you about, paid £22 plus £5 delivery for it and it works perfectly.
Mark said already he had a problem with the same symptoms as yours is showing on Mike Dundees 2.6 and when he put my new MAF on it to try out the problem disappeared......
Dont know why you want to go genuine when the one Mark recommended to you is perfectly good quality.....??
Anyways, your choice
:)

I know what your saying bud, but if it turns out the MAF is the problem then i'd be reluctant to buy another cheap MAF as the one that is possibly causing the problem is brand new.
Fair enough it might be a one off and i'm just unlucky that I got a dodgey one. :-/
I have now put the original MAF back on which basically doesn't work and the EML is back on. If the problem in the morning has gone then its a safe bet its the MAF, if the problem is still their then the investigation will continue. >:(
Hope all that makes sense!! lol
-
Have you given the cam sensor plug a clean and wiggle?
30 seconds sounds temperature related. Worth a shot mate

Thanks for the suggestion, I will maybe get that done at somepoint anyway.
Good News though, I started up this morning with non working MAF and no backfiring or splutering as it normally does. The idle was fine but when I put it into D the idle was a little unsteady as if it was going to bugger up but it didn't, just kept hovering up and down a bit. Car drove off fine without loss of power or throttle twitching etc.
My Conclusion - Need New MAF :y
Only one decison left, Genuine or Made in China (lol)

Get the made in China one, as I'm certain that's the one Mark fitted on mine :y.........honestly ;D
-
Thing is the one thats caused all the problems is a Made in Chine one.
Not saying that they are all bad but I just have bad luck.
Really could use one before I go to Leicester tomorrow morning and I don't think i'll get an after market one from anywhere today.
-
Good News I think we can finally put this thread to bed, I bought a new MAF yesterday (Genuine from Auto Vaux @ £107 inc vat was better than £187 from VX) Yes I know I could of got one cheap but I feel better knowing its got a genuine one in.
Car is back to normal and I have managed to get a refund for the cheap dodgey MAF. Result.
Thanks for all the help on this, just a shame the engine management codes sent me down the garden path with the throttle body etc.
Which reminds me, I know have a spare throttle body for sale! :y
-
lets hope so :y
fingers crossed :D
-
Lol, told you it wouldn't be the throttle body didn't I, eh eh eh eh ......but no, you wouldn't let it lie, no you wouldn't let it lie!
;D ;D ;D ;D :y
(Joke, of course!)
-
Cant believe how much you paid for that MAF mate.......!!!!
You could have got the one recommended AND bought a tank full of fuel for your run today for that much wonga........
Never mind, all sorted, thats the main thing.....!!
:y
-
A good result in the end, OOF helps out again 8-) 8-) :y
-
Glad it's sorted. I've been there and I know the huge sense of relief you will be feeling (plus a small amount of apprehension for a week or so ;D)
