Ive gone thru hours reviewing the topic of Renix High Idle at Startup and havent found anything that seems to fit the problem on my 88 XJ.
As the subject line states when I start up my XJ it revs up high (no tach to watch) for 8-10 seconds. Then it settles back to whatever the idle speed is. Other than that everything is fine. Its done this for years I think. Ive had the IAC out and it lookks fine. DOnt know if it moves or not when the XJ is running.
Today after I got to work I removed the electric plug going to the IAC. After work I started the XJ up and it started right up WITHOUT the High Idle at Startup. The Jeep ran just fine all the eay home with a couple of stops/starts on the way.
Ideas? Im wondering if it could be the "latch relay".
Thanks.
