Hi,

I'm a newbie to Vauxhall never mind the omega so you'll prob here from me a lot here. I've already introduced myself in the Newbie section so lets get down to business...

Just bought a 3.2 V6 Omega and had it fully serviced, timing belt changed before starting to drive it. Since i've got the car back i've noticed rough idling from a cold start, moves up to 900rpm then drops to 450rpm etc. Even when warm the car shakes a little. Then I took it for a drive, put on the "S" button (AUTO TRANNY), floored it just to feel the kick down, and at about 4500rpm the engine hesitated and engine light flashed for about 10 secs and then remained solid. The car then limped, nearly cutting out untill I turned the engine off. Started back up and the light disapeared, engine back to normal.

I know I should take it back to where I ahd the work done, but to be honest i'm in Dubai and I made the mistake of doing it on the cheap - so i'll probably get told it's something else and cost me more money.

Is it likely to be anything timing belt related? I'm a little concerned incase i'm damaging the engine.

Let me know your thoughts,

Geo

inital estimation : cam sensor problem

The poor idle - probably an airleak somewhere

for the 4.5k hestitation, read fault codes (see Maintenence Guides for Pedal Trick), may give some clues.

Also worth doing fuel filter if you don't know when last done.

Excellent, once i've checked the codes i'll post them back up to see what you think.

Thanks
