Greetings fellow Maxima gurus,

I have a 90 SE and an 88 SE and just last week the 88 started reving up and down on it's own at idle. At first I thought that it was the throttle position switch. I cleaned and adjusted it and it seemed to run better at idle for about 30 seconds . So after some investigation found that whenever lightly pulling on the conductors that run to the coolant temperature switch, it could reproduce the problem. I can make it idle from 800 to 1100 just by doing this. I have yet to ohm the switch, but has anyone seen this? It's got to either be the connection on the switch or the switch itself. I figure that the ECU must be getting conflicting signals of hot/cold condition which is causing the cold injector to not fire/fire...not to mention other vaccum control devices that supply vaccum to devices when coolant reaches a certain temp.

Any ideas???
Jamie
