Last Saturday, as recommended, I cleansed the idle control valve with carb cleaners and was able to dislodge a lot of dirt inside. Reconnected it and while the air cleaner was off, I tried to start the engine. That did not solve the hard starting. What surprised me however, was that the throttle valve kept on moving erratically (closing and opening) while idling. If I recall it right, it should not open at all while idling. I disconnected the CIS-E control unit and the throttle valve stopped moving. Kept it disconnected and used the car that day without any problems. In the evening, I took out the control unit, OVP, and another relay with some German name on it "Kalstart". Opened everything and sprayed it with a contact cleaner that I just bought and reconnected everything back.

I don't know if that solved the problem, because I did not take another look at the throttle valve.

But what I'd like to know is what causes the throttle valve to act that way? I'm tending to believe that the control unit is my main problem since my idling somewhat smoothed out when it was not connected.

I would appreciated anyones help, pleeease!!!!
