Persistant high idle when warm. 200 83

posted by  someone claiming to be Alan Petersen on  Fri Nov 24 11:31 CST 2000 [RELATED]

Hi all.

I've got this high idle problem with my 245. I have checked the archives and played with the reults to no avail.

The car starts normally then the idle gradually rises till it is around 12-1500 rpm.

So far I have replaced the coolant sensor for the LH-jet and the constant idle valve. I'v also looked for vacume leaks and screwed the idle adjust all the way down. I removed the throttle body and cleaned it out, made sure it was closing fully. checked to see if the throttle switch was "clicking". I also looked at the cable and it was fine.

I can close the hose to the constant idle valve and the idle drops down to around 300 (with the idle adjustmend screwed all the way in).

The harness appears to be fine. When the coolant sensor is unplugged, the idle races to around 2k+.

Any suggestions would be helpful.

Thanks in advance.

Alan
