Cleaned TB, NEED HELP! 700 1990

posted by  someone claiming to be 90gl740 on  Fri Oct 7 13:40 CST 2005 [RELATED]

Hi I have a 740 Regina system and I recently cleaned the throttle body (again) and adjusted the TPS as per FAQ (since I accidentally moved it). When I first started it, the idle was at 200-300 RPM's (never heard an engine so quiet).

Then I tried to adjust the idle like it says in the FAQ but I was confused.

It's idling at about 750 now, but the car shakes when I come to a stop. I tried adjusting it higher, but then the TPS won't click when it comes off the adjustment screw.

What is the proper way to adjust it? Should I have it set so low that the IAC is on all the time or just when I let off the pedal it clicks on?

Also, at idle is the IAC supposed to be on all the time...to where you can hear it moving back and forth constantly?



Thanks,
