Omega 2.2CD - Acceleration Delay - Vic_Abbott
Hello

I have a Y reg 2.2 CD Auto (petrol) Omega which I have owned since July with 40k miles and FSH. Please could you offer any advice on this peculiar problem I am experiencing.

More often than not, when I pull up in traffic or at junctions and then proceed to pull away again, the engine does not respond at all, no increase in revs, nothing. There seems to be a 3-4 second delay after I press the accelerator pedal before the car moves. I find this an alarming and dangerous situation to be in as I never know when it will happen.

I have checked the condition of the multiplugs around throttle sensor in the engine bay, and also on the pedal, and found nothing odd. I have also changed the Lambda sensor following a recommendation, but sadly nothing.

Thanks in advance if anybody can help.

Has the ECU light come on at all? Total guess here, as the engine is "fly by wire" (in other words there's no throttle cable) it *could* be a dodgy potentiometer on the throttle pedal.
