1996 Jeep Cherokee Sport 4.0 Won't Idle
|
|
|
We recently braved a pretty decent storm here in NW Texas earlier this week. Tuesday, the day after the storm, I attempted to start up my '96 Cherokee Sport. It turned over but would not idle. It sounds as if it's turning over normally, and actually sounds very good, yet it idles for a split second before the car dies.
However, stepping on the gas while starting the ignition and holding the accelerator keeps the engine operating, though it shuts down again just as I take my foot off.
Research led me to believe this could be an air flow issue. I went ahead and cleaned my Idle Air Control Valve, though I found that it wasn't even especially dirty in the first place. Cleaning it out did not help.
It was relatively low on gas before parking it (outdoors, I don't have a garage) through the storm, so I hiked to the nearest gas station and came back with a gallon of premium, Still. no dice.
My battery has plenty of juice and the alternator seems fine enough.
I obviously haven't completely addressed or investigated the air flow issue, though I may very well have a fuel pump issue. I am not a "car guy" and have little mechanical knowledge beyond the very basics. I am guessing my issues will require a mechanic, and I have a guy, but I would like to have a better idea regarding what I am dealing with before taking it to him.
Please ask for any other details I may have left out if you think you can make a suggestion. I would greatly appreciate any help and am anxious to hear some ideas.
Cheers, Aaron.

If you have to keep the engine idling by feathering the accelerator pedal, you have an idle air control issue.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I clean the solenoid, so that is not looking to be the issue, unless the solenoid itself is not operating for whatever reason.
What factors may effect the IAC? The electrical connection not causing the solenoid to act properly? Air flow?
I may then go ahead and buy a new IAC and replace it, but I do not want to make a purchase that will have no real effect should there be other factors present.
Any ideas where I should further investigate or look a little deeper?

Don't assume simply cleaning is going to fix anything. It's an electrical stepper motor. Washing it doesn't fix anything electrical.

With that in mind, would there be anything else that would influence the IAC's being functional? I don't mind replacing it, however if there is a cheaper, simpler, different alternative that may be causing my issue, what could that possibly be? Any ideas?

Well, maybe you should try a wash and wax.
