I have a 92 Cherokee Loredo, 4.0 HO, automatic, 2wd. It has been idling kind of fast, around 1000 - 1100, and when I come to a stop the engine seems to be still pulling, like the trans has not yet shifted back to 1st gear, and when I release the brake to go again there is a very noticable clunk coming from somwhere in the drivetrain. I have checked the engine for vacuum leaks, checked the rearend for play, checked motor mounts too and found nothing wrong, so far. I looked for binding spring leaves, loose shocks or mounts, and even looked over all the brakes. As to the idle speed, I have not touched any idle sensors or adjustments yet. Where should I look next?
