View Full Version : 96 XJ stalling

Brothers 96 XJ 4.0 stalls every now and then. He says the idle starts to drop and sputter a bit before it finally stalls. Only happens sometimes, but I'm thinkin about just cleanin out the Idle air control? I'll take a look around for vacuum leaks as well. Just gave er a full tuneup a few months back, but its been doin it before as well. Any other pointers you jeep guys got would be great, thanks!

Does it do it when it's hot? Mine used to do that, turned out to be the CPS, Either that or IAC or TPS, there cheap to replace so I would replace em anyway,

How is it to restart after the stall?

Well I picked it up on saturday, and as soon as I started driving it, there was a definite stumble/hesitation, braught er home and pulled off the throttle body. Cleaned the crap out of the IAC and the mass air flow (I think, had a little black 90 degree hose going into the throttle body), and now it runs like new.
