noticed car was juddering in drive (auto) last night when at lights with foot on brake thought time to service car.
Wife went out later rang home saying coolant check had come up on dash and car ticking over rough.
so today thought I would clean out the breather and throttle body using the forums wonderful pages.
Still rough idle, tonight replaced spark plugs (no 4 dark rest ok).
Still same.
When first fired up from cold ticks over ok but after driving for a minute it starts to run rough on tickover, I am thinking HT bank breaking down??
had to fill coolant up seemed very low is this a differant fault or part of same problem?.
checked oil no water in it.
engine management light always on.
can you wnderful chaps shed any light.

is nobody able to help need car for work if its the coil pack i can try and get one tommorow
-
would think MAF gone or the wires need cleaning on te wiring clean all wires up and see if that works, but you should have the ECU read to see what codes come up :y
-
thanks for that i live in preston lancs is there a member close by that can read codes dont really want to go to main dealer.
-
i dont know but if you leave it for to night some one near to you with a tec2 may leave a message :y
-
good thinking batman
-
is this on gas or petrol?
-
started doing it on gas now on petrol

with caution, i'm thinking ignition system and a water leak. Would be nice if you could borrow a good coil pack from a member near you, swap and see if it behaves, cracks in the plastic or torn or soft rubber boots, any signs of damage etc. Oil in the plug wells will not help at all if present. If new plugs swap plug 4 over in case its duff and see if the colour goes with the plug or stays wi th that pot, if the latter would look at c pac.
Clean mayo free oil is a relief.
I'm cautious as it would be nice to read the codes before going any further. On the 2.2 thats not possible without a code reader.
Water leak, first place to look is hbv. Well covered on here. Guide in maintenance.
-
as mentioned you need to get the codes read. Might be worth getting the 'cheapo' version off eBay for £30.
I would be thinking coil pack, whats the miles on it? Mine started to go at 110k not miss firing but would judder under load at low revs.
But before you go changing anything, get those codes read!
-
what a good idea can you read all the codes with this reader off ebay and if so is it called a tech 2 also

An explanation of the different code readers and what they can do (and how much they cost...)

Miss Firing?
I bet she's hot stuff!! ;D

latest news work at college didnt know we hads bosch diagnostic gear clever stuff blue tooth to computer showing how my car running.
my colleague said the fault was on ignition to cyl 4 which i was hoping he would say as it was this plug that looked bad.
so went and bought coil pack fit it and no differant.
when i looked at no4 coil on my old unit i am sure i could see a very fine crack so everything seems to point to coil pack so why is it still faulty?
do i have to reset the codes any help out there
-
reset them and see if they come back, if its got a crack in the DIS pack, thats not good.
On the up side there are not too expensive and easy peasy to replace
-
sorry didnt make it clear got new coil pack in now so you think resetting will clear fault how do you do this
-
you will need a code reader to do this, either cheapo, or genuine tech2
-
aw.....maybe HG after all then. Did you trace the leak? Anything showing in the engine bay? Any smell of burnt coolent?
Good plugs and coil pack, only thing left to check on ignition is wiring to coil pac. Is the connector ok? Not broken or cracked? Any corrosion on the contacts? Bare wires etc.
Just clearing the codes will not clear the fault. If it was running ok the codes would still be there and still need clearing. Car will run with old codes present.

crikey proper night owl
thanks for that I will have a look this morning to see if anything obvious on loom.
nothing obvious on the water front but when i was cleaning out the lower breather pipe (the one from near exhaust) it had a slight milky gunge even though oil ok are you thinking worse and if so how big a job to change head gasket
-
started car this morning smoke pouring out of back steam coming from rear of engine smell of coolant and slight milkyness in top of cap I think that means HG so next question how much is this going to cost me? too busy to do it myself so can anyone give me an idea, my friend has recommended a reliable mechanic.
-
Sorry to hear that. I've read its not too bad a job on the 4 pot. Daz(Darth loo knee) on here may be able to help. But preston is a long ways from his native Stoke.
