On my 96 GCL 5.2L I've changed out my IAC and Ignition coil. The coil helped the really bad idle where it almost stalled. I changed out the IAC but did not adjust it initially. Last week I took it out and pushed and turned the pintle until it was 1 1/8 inch. I wonder if it's ruined since I didn't adjust it the first time. The Jeep idles fine with the AC running but with the AC off it idles real rough. Thanks for any insight. SJ
