I have a Omega with the 2.2L Y22XE engine and I have some serious misfiring troubles. Last couple of days it has gotten worse. Before that you could get it to run on all cylinders by restarting it. It idles very rough even if it runs good on higer revs.

I suspect the EGR or the Dispack.

I got the following error codes out of it:
P0302-001
P0304-001

Before I cleared it I also had a TPS error, said something about wrong position under load. That can be explained by the poor running and when the pedal is pushed nothing happens, it just bludder.

I have read a few threads here and my clues are none except what I said before. I want to be more certain before I dig in to it.

My analyze software have a function of testing the coils but i can't get anything out of that, it doesn't report anything.


Thanks

2.2 doesn't have egr on UK cars  :-/

Codes are cylinder 2 and 4 misfires - check plug wells for oil or water.

[Jan Suhr]

Thanks I'll check that. I am in Sweden so it has a EGR.

sweden if i remeber rightly has nearly the strictest emission regulations in europe. learnt that from an episode of top gear

My Y22XE engine 2000 MY does have an EGR. And it is a UK car. I think that the Z22 engines were with out the EGR.  :

Getting back to the problem my miss firing way back was down to the oil getting into the plug holes.

I took it appart today and it was bry in the sparkplug holes. Some small traces of moist but nothing that was wet.

I had water there a few years ago after an engine wash but that I did blow dry with my airgun.

Number 2 cylinder is clearly firing pretty bad. Piston and sparkplug is wet. Number four did look dry on top of the piston.

I will replace the sparkplugs tomorrow and see what happens.

BTW is there any way of testing the Coilpack?

hi.had low voltage reading on no4 on my 2.2.cleaned plug to injector and that cleared the problem,my uk car also has egr valve.

[Jan Suhr]

I have now put in new sparkplugs and it got a little better but cylinder two seems still to be dead. I still have the P0302-001 code.

My analyze program has a Ignition Coil Test Program and it ask for some plug to connect. Anyone knows what that can be?
The testprogram shows over 12 V on each cylinder.


I strongly suspect that my Coilpack is bad.

Anybody with some opinions?


Thanks

In Swedis: P 0302, cylinder 2 = misständning upptäckt! Samma gäller P0304 fast här är det är cylinder 4 som indikerar fel.
Orsaken kan vara;  Mekansikt motorfel, ledningar, tändsystem/bränslesystem, insprutare, motortemperaturgivare/luftmassamätare, motorstyrdon.

Thanks for the reply Krax,

I think it doesn't fire the plug properly. The injectors are probably working OK since the number 2 plug and piston are wet from fuel when checking that.

I'll see if I can find a coilpack DIS tomorrow to try with.

Thanks

Agree coil pack, check the rubbers are not split(vx uk do a pack of 4 rubbers) and also check the new plugs for carbon scoring, black lines down the insulator, this also suggests the rubber plug(to spark plug) is bad.
Also check for cracks on the coil pack itself around the square blocks(iron cores?) at the base.

If its dark you may be able to see the spark escape when engine is running.

I got a coilpack from a junkyard and it cured the misfiring problems, it now runs on all cylinders.

thanks for all help.

Now to the next problem with my leaking intake...
