Just had a run out to drop something off to Mark on the way back when i stopped at some lights it seemed a if the car was idering a bit low as if it was about to cut out be it did,nt.
When outside the car sounds of if it is chugging and there is a diff sound that normal from the backbox...almost as if its not fireing as it shoud :-[ :-[ :-[
Car is not in limp mode and no greabox message ....can anyone help a point me where to start. :'(.
Thanks
Steve.

Check the gas flow from the rear box ... you might have a silencer starting to breakup .. this will give "horse hair" like wire-wool out of the box .. and causes restrictions to the gas flow ....
This happend to the old miggy ... new exhaust soon sorted it .. :(
Checked by taking the back box off and suddenley the car ran properly again .. :)
-
Low on fuel?
Misfire? Any codes stored or EML on?
-
Did you ever get the oil cooler sorted?
-
Plugs? Dispack?
-
Hi yes thanks Oill cooler all done car just had MOT and was fine on emmsions. Full tank of fuel seems to give a bit of a judder when picking up speed. No new lights have not checked for codes....Need to use the pedal trick but have frogoten how it is done :-[.
Thanks for the tip about Silencers will give them a check.
Anything other to look for.....Was thinking Crank sensor but not sure if that would give these probs :-[.
Thanks
-
Worth a pedal trick Steve, see if any codes stored and post em up. link below, paper clip dont work on yours.
You have a new cat back exhaust iirc? HTHhttp://www.omegaowners.com/forum/YaBB.pl?num=1189022687

Steve, as yours has a new silencer I very much doubt that it's suffering the GM silencer issue message.
Pedal trick is brake and throttle to the floor and turn ignition to II, DO NOT START IT! Then count the flashes
Also check that fuel pipe...... you know the one!
-
Was thinking plugs had them done last year which would have been about 20 k ago. This was before having rockers done afew weeks ago/
-
Thanks will check now and post back/

Just edited my post above... Check the fuel pipe that you've had problems with before.

if its missfireing pedal trick will tell you. 0300 random missfire 0301 missfire cylinder 1 and so on. iirc. 10 flashes equals zero.

Both pre acts(ignore, normal on your car) and missfire on no 4 pot. Bet the others are missfire codes as well, pots 2 and 6 perhaps?... All codes should be 4 digits. Could be coil pack or oil in plug wells.
-
Thanks guys ..just rechecked
0302
0300
0303
i think ..would you think that would point to the same side coil pack...
and is it looking like it could be the pulgs over exhaust.
When i just started the car it sounds uneven as if not working on all cyc.
-
Something odd there as you've got misfires on both banks and I find it hard to believe that both dispacks have failed at the same time. :-/
-
Dundee had a similar problem and if i remember rightly Mark mentioned something about metal from the coil pack on the spark plugs....
-
yer that is odd car starts just fine not sure if because the old plugs where used after rocker cover done that could have broken down to a point to give this prob. :-/ :-/.
Will check the fuel line and see if there is anything there. What a PITA :-[

Exact same codes i had in my car when i bought it, but it was not missfireing then, they where old codes. You have middle left pot, 3, on drivers side, and front right,2, pot on pass side iirc. Oil in wells?
How old are plugs?
-
Thanks Loo Knee that something to check on i remember seeing that afew weeks ago.
-
change plugs and check coil packs for cracks while your there. Easy diy Steve. You can do it.
-
Have a look at this Post i have just hunted for maybe it may help :y

Just had rockers done afew weeks ago and on leaks on covers ...Plugs are about 20k old and where done last year ...but this was befor finding the rocker leak last month. .. I,m thinking that becuse the old plugs where reused they may be the prob.
As i did not see the way they looked before they where put back in i,m thinking they may have been on there way out if they have oil on them at some point.
HOPE it not the coil pack as i know there ££££
-
Thanks for finding that L K and i will give the them a check Chris
Thanks for your help ...Will update on how things have gone
-
No probs hope you can get it sorted :y
