I know it's not a vectra C but hopefully someone has an answer as its bugging me like hell.
My current car (95 vectra 2.0 SRI) has got a very annoying problem. Basically the car revs too low at idle (sometimes stalls or shudders) and when i pull to a stop at junctions it often cuts out. I can solve the problem by tightening it up a little however a few weeks down the line I have the same problem again and have to tighten it again. It has got to the point where im running out of screw thread The airflow jobby which the ECU (i think it is the ecu anyway) plugs into has been changed with no improvement. Im about to sell the car as Im getting a vectra C, and I know I can temporarily fix it with a couple more twists however I'd prefer a more perminent solution for the next owner.
Also the onboard computer display doesnt function now and simply says "program" is there a way to reset this or is it ******ed ?
Any help would be appricated
