I have a 2000 Cherokee loredo, it had one owner, until I bought it, has been great. Then it started to spit and sputter and stall. but would start again. One day my wife was coming home from work and it stalled going down the road and would not start. We had a friend come over and he sprayed either in the air intake and it started an ran great for the day, and then spit and stalled on our way home...I got it started and made it home and it stalled coming in the driveway. I had a friend replace the fuel filter and now it wont turn over at all, even with either. I am on a medical pension and cannot afford to just take it to a garage...if anyone can please give me an ideal what it might be.

Re: help
Welcome to the garage.
You have really a cherokee, or grand cherokee?
Stalling problems many times are caused by a failing crank sensor.
I would start checking for stored fault code(s). If you have a grand cherokee, you can check it using the so called key dance: ignition switch off/run three times and leave it in run at the third time. The odometer will show "DONE" when all ok, or a fault code(s). Let us know what you find.

Might want to try cleaning your IAC valve too.
My ZJ behaved exactly like that until I cleaned mine.

Yes is a grand Cherokee, sorry. I will try both suggestions thank you all so much.

Re: help
If it would turn out to be the crank sensor, then here is a writeup on changing it on the 4.0:

Re: help
I did the key dance, it came up done immediately.

Re: help
Then cleaning the IAC plunjer and air canal would be a good start. Over time a lot of dirt builds up and the idle speed can't be controlled right.

Here ya go

I should have said, the full name is idle air control valve (iac), should be sticking out of the throttle body.

Eventhough the position is almost the same, he has a 4.0.

Oh you're right, I missed that. But, yeah, process is basically the same. :-)
