So, I have a 1991 jeep Cherokee with the 4.0 inline 6. I've read lots of threads about the same issue, (low idle and stall). I have replaced the battery, IAC (deep cleaned the throttle body.), TPS, CPS, and temp sensor. i sprayed the vacuum lines with starting fluid while running and no difference. I have noticed a loud suction sound coming from the front of the intake but no clear cracks or anything. I also replaced the spark plugs because they are black and the coil pack because I had orange spark. I'm out of ideas and have no clue what to do any more. would love the help in trying to figure this out. Thanks.
