What do you reckon is the problem? Vote for the number one favourite and I will let you know when the problem has been diagnosed.
My Omega is starting to run very badly. It is particularly noticeable when I begin to accelerate. Then it clears and then it comes back again. No water loss, new plugs last July. FVSH from new. It seems to be getting worse. There is a bad egg smell coming from the exhaust.
From a complete amateur who hasn't a clue? :-[
Sorry should have said it is a 1999 old shape Elite 3.0 V6 auto.

Have you tried doing a 'paper clip test'? http://www.omegaowners.com/forum/index.php?topic=90581.0
Code 19 would be crank shaft sensor ;)
-
Smell is due to inefficient burn so could possibly be dispack/leads/plugs breaking down
-
My monies on the coil pack , same happend to mine ;)
-
Hmmm. All very interesting and thank you. Should have mentioned it had a new coil pack in 2008.
If I get a code error is it advanced enough to say whether a plug is down or does it just give a general area?
-
You car isn,t burining the fuel that is being injected into the bores hence the smell.
If dis pack is fairly new and you have had plugs changed,albeith at GM Dealer then my money is on one of the plug leads not providing adequate power.If you have heard any misfire or popping from the exhaust you might also have a slightly loose plug .

Id say a mixture of not enough air eg blockage or leak and the smell may be the cat

FVSH from new is the problem :-X ::)
More seriously, it's probably an ignition fault and I wouldn't be surprised if all of the plugs haven't actually been changed ::)
Do the paper clip test and come back to us :y :y

Is there oil in the plug wells?
-
I'll need to check. I abandoned the car at my parents who live a fair distance away so I won't be heading back for a week or so to check. ;)

I would hope not. All the plugs should have been changed. It was the big service and cost an arm and a leg. All we be revealed soon and if not the AA will be towing me back! :y

I see you're fairly local... If you need me to pop around and have a look for you I'm sure it can be arranged ;)
Also, don't forget the Essex Meet at the Ardleigh Crown on the 7th ;) There'll be quite a few people around who can look for you :y
-
It's a bit far away at the mo but I the meet sounds good! I will be there hopefully :y
Any details re times?
-
Look in the meets section.... Probably about Midday onwards :y
-
Its traditional for VX dealers not to change the plug on number 6. ;)
-
Okay guys, the 4th Emergency Service sorted the problem. Well, sort of!
The chappy found, "All three plug recesses were half filled with water."
He dried out the water and removed the spark plugs but they were fine, re-assembled and it's all spiffing.
BUT he couldn't work out where the water had come from. The only thing he could find was a sponge under the windscreen which was sopping wet. It was on the battery side of the engine.
He'd never seen the water problem before. Any ideas wise and learned engineers?
-
I've taken mine of, had rain all night and most of today and it's all dry at the back of the engine!
-
Sorry do you mean the sponge? Is it a bit of a problem from past experience?
-

Yeah, it's fitted to the underside of the scuttle... There is also the foam seal between the long section of the scuttle and the cabin air inlet box.
Sorry, just re-read your post... When you say "sponge" Do you mean a sponge or the sound deadening pad???
-
Good question. I don't actually know. I think we assumed it was a sponge! :o
-
Meant to ask, has anyone else had this problem? Could the water be coming from elsewhere?
-
Leaking scuttle is a well known problem on Omegas Greg :(
I can't see water getting into the plug wells from any other source tbh :-\
Usual fix is to dry out the 'sponge' then run a bead of clear silicon under the scuttle joints and around the base of the wiper spindles where they come through the scuttle? Hth matey :y
-
A bad egg smell you say? when i was working at a garage a couple years back we had an 07' MK3 Mondeo 2.0 Zetec come in and he complained of a bad smelling exhaust it actually turned out to be the Cat and we changed the coil and leads as a matter of precaution so it might be worth considerering as it cured his problem long term aswell to save him getting a new cat for future MOTs :y, Expensive solution but it might be what it boils down to.

Thanks PhilRich. I'm assuming the scuttle is the plastic grill thing with holes in it?
Thanks Sam but the bad egg smell went as soon as the car was running on 6 cylinders.
-
Yes Greg, the scuttle is the plastic cover that hides wiper motors, pollen filter etc and extends from the windscreen base into the engine bay. It is in two? pieces iirc, with the longest section on the drivers side. :y
-
I've noticed that the rubber surround that should be fixed to the scuttle has come adrift. I just need a dry 5 minutes to re-attach it! :-\
-
Thanks Guys. All sorted and my car is running like a peach.
V6 3 litre..... what a smooth and beautiful beast. :y
