hi- my 02 cavalier always idled smoothly with the air conditioning on, now it surges from 600 rpm to about 1000 rpm, constantly while at a stop sign, and you can hear the AC relay clicking on and off. I need to either shut off the ac or put the engine in park to stop this from happening. It also seems to occur well after the engine has warmed up. Thanks for any help! -Tom

FYI- fixed! There was a bad electrical connector at the A/C temperature sensor. I noticed that the problem got worse when I jiggled the wire leading to that connector. I replaced the connector and problem solved. The part # is 88988301 - it wasn't cheap, $56 at the Chevy dealership. Rockauto.com has it for $31.
