Hey, new to the forum. Longtime viewer first time posting.
I am looking at picking up a 96 Xj 4.0 auto A/C But one thing that has got me worried is its idle. Let me explain.
Starts and runs just fine. Has plenty of power and no noises. BUT, about ever 15 seconds almost clock work the idle jumps about 500rpms then goes back down. I thought maybe IAC so i pulled the IAC plug while runninga and the problem seemd to pretty much go away. It was running just a hint rough with the IAC unplugged but i plugged it back in and the problem came back.
There is no CEL but i am wondering if there is one in memory. Is there a paperclip way like some to jumper the connector or do i do the on/off/on/off/on trick like my 93 ZJ.
AM trying to diagnose this before the purchase.
I have also searched thru the forum and found many threads to the IAC but nothing with my symptoms
Any help would be great
THX
