my problem is not solved, omega 2,5 V6 BJ 95 jerks while driving,in empty run everything tuti,no error diagnosis. at 80kmh highway ok from 100/110 jerks the car,various opel dealers are not able to find the error and this is 26/11/01. Now I just have the cylinder head checked(cost 86.- euro) compressions tuned but,opel has checked and read out. So slowly I have the snare full of opel,which promise a lot and hold nothing(see if you see the has no one had such a similar problem and can give me a good advice? You can also mail me [email protected] Thank you in advance:-))
