Try replacing the cam sensor first. If it does not fix it, then it's the ECU; open the ECU and replace the IC 93.67.29 that controls the cam sensor.

Best of luck!!

I have a 1998 Vectra GT, and have just found oil in the throttle body, and after reading this forum, I have had the same issues. Can you please help me out?

Hi, had the same problem, changed all sensors, still the same problem, and then sprayed carby cleaner around the manifold and was sucking it up. The problem was a faulty gasket; replaced the gasket with double gasket and paste, and now it runs like a rocket for a 2.2 and idles around 650 RPM. The procedure took 1.5 hours to do.
