Hi folks,i have today spent nearly 3 hours at my mv6 and it still nae better.I have cleaned throttle bodies,taken of plenums,cleaned all the breather pipes,checked all the vacuum pipes,cleaned spark plugs,checked all cables and connections and it still has a mind of its own,when i touch the pedal it rises to around 2000/2500 revs and sits there for around 10 secs then drops to idle at 600rpm,anyone any ideas what this is as its doing my head in!! when slowing down to road ends it revs up and when changing gear it sits around 3000rpm,seems like throttle sticking... i have only acces to snap on solus which doesnt really give any depth in live data,it drinking the fuel too... help me please before i go mad and sign meself in!!
-
throttle position sensor is a possibility..lets see what other members think ..
-
i'd say icv :-/

You didn't mention having cleaned it :-?
-
no icv or egr,what is the electrical unit on the side of the throttle body,is there anything mechanical in there to be cleaned?? Not showing any throttle faults etc on computer,only fuel trim fault but this is due to cats being removed
-
is it an air leak somewhere, or perhaps a dicky non return valve for the servo :-/
-
I'd be using a family size can of carb cleaner under the bonnet while it is idlin'g.
Sounds like an air leak to me.

tps..
-
classic air leak symptoms in my experience, but then i've no experience of drive by wire issues, no fault codes i take it?
How far down did you strip it? need to go down to the seals under plastic wedge in the v and work back from there if there's nothing obvious, but sounds like you've already done that, back of the main vac pipe from to plenum is classic for waring through on the air con pipe next to it, any hissing dieing out after the engines stopped? any hisding at all come to that?
-
I'm gonna go round her today with carb cleaner,see if that makes any difference,does seem like an air leak,would there be anything sticking in the throttle position sensor,its the only thing i didnt open,any mechanical in there that needs cleaned??

tps can not be cleaned.. its an electronic part..
-
cheers :y
-
No difference with carb cleaner sprayed round her,whats the vacuum box at front of vehicle down at pulleys,2 vacuum pipes coming from it,would it be anything to do with this??
-
Just also noticed that it doesnt do it when cold,after 5mins it will tho,your bound to be getting sick of this but me having a blooding nervous breakdown here :-/
-
More news today folks,missing and backfiring now,coming up p0120 and p0220 faults,throttle postition switch a circuit low and throttle postion swtich circuit high,could it be the sensor on the tb's?? also coming up random misifire on all the cyclinders,major loss of power,also tried disconnecting the airflow but no different... anybody please?? really doing my rag in now :'(
-
Is it normal when you turn car on the tps will make a whinning noise then cpl of clicks,stop for 10 secs then same again?? i can perform an actuator test on the tps and it seems to be opening and closing ok

normal. :y
er re read, it doesnt go on indefinately, but the noises you describe are certainly normal.

imo buy original unused vx throttle position sensor..
-
i had a vectra v6 2.5 before the omega,and bought ported and polished tb's for it,i mite have the old tb's kicking around the garage,would the sensor be the same??
-
Just looked,it different... will price a vx one tomorrow,thanks again :y

Ok the news today is that i phoned a cple of our suppliers today,one said that the tps sensor they can get is not matching up with my chassis number,the other is getting back to me,i can get a 3 pin one but mine is 6,also phoned up vx dealer and they said the tps doesnt come separate and need tb's,costing me over 300 squid,anyone any ideas about this,the car is parked at work,as it wouldnt pull ye outta bed.... cheers

visiting breakers and asking to test a known working one.. :-/
-
Is the 3.2 the same as my 2.6 tb's?? See one on ebay

Another one on gumtree,looking over quid and wont sell the tps separate.. arrrgghhhh >:(
-
google heathrow omega breakers, or post wanted add in test zone and ask Jimbob to move it to parts section.
-
Tried a cple of places,cant really locate a decent one for humble money,gonna order a new tb tomorrow from vx dealer,at least i get warranty and nice shiny new one,only problem is it has to come from germany and may be 3-14 days,trade price is a bonus...keep you posted...thanks again for your time everyone :y
-
just tried the new tb's today.still not starting,no faults,doesnt seem to be getting fuel,which 1 is fuel pump relay?? can it be checked or bypassed

did you have starting problems before :-? , cause there is no starting problem mentioned in the post..
-
The car was revving up for a while,then missing and backfiring,put on comp and tps faults showed,after a day the car would not start,put the new tb's on and still nothing... getting loads of fuel,no faults shown,done actuator tests on pump and tps,all good... car grinding and firing,keep grinding and it nearly goes... good compression etc,could it be the crank sensor... seen this before with no faults showing and it being that... am going mad here,tb's cost me 333 squid

could be .. but dont rush..
did you have intermittent starting problems before ?
hesitation ?
-
Never had any starting probs before,always on the button,cant understand it,does anyone know the ohm reading to check the sensor?? was looking thro autodata but it doesnt list it

I think you must see some other codes stored with p0200 and p220.. :-/
anyway, from some old info I know it can be tested with voltmeters.. let me check..
-
here is some info
http://www.ehow.com/way_5471047_do-check-crankshaft-position-sensor.html
and another way to for checking it,
pass some ferrous metal very close crank sensor to it and check the voltage jump..

Cheers mate,will check it tomorro...hopefully its handy to get at on my motor,have car sitting down at work but its too rather heavy to push on to a ramp by myself :-[

I hope you will sort it.. good luck..
and safety first.. :y

Where would you find the location of the sensor,any pics on the site?? not asking much am i ;D

Thank you people,will try removing and cleaning tomorro,keep u all posted :y

I had the same fault a while ago after i put cleaner down the bag pipes (air intake). It misfired and the revs were high.Maybe air mass meter?

Just a quick update folks... went to check the cs sensor today and there was 2!! somebody replaced it before and just left the old 1 there,took out and cleaned,no difference,stripped of plenum again and checked everything... all ok... tried towing the car and it nearly started slightly... turned car over and started running but missing badly and backfiring like a wild bore on the job... next thing i disconnected something and the car run 100% and is going better now than ever before...
3 guesses to what it was...
a fart in a bottle to the first person who gets it right :y
