You are not alone. Our 2004 JGC did the same thing last week and then again this morning. The battery is less than a year old with no corrosion on the wires or terminals.

04 Grand Cherokee slow idle by rosebuddove

My problems began when a large tree branch fell on and around me while driving. I ran over some small branches. I heard a noise and check to see if I had a branch in a tire. Nothing. I was 40 miles from home. I got gas. The jeep sputtered for the first time since I had it. Shortly after the check engine light came on.
 
A tester said it was a P035 issue. When I checked the jeep computer, it said the same thing. My son drove the jeep and the light went out. It came back on a couple weeks later. When I called the garage, the man said the jeep's computer is not accurate and neither was the tester my son used.
 
Regardless, I chose not to visit the mechanic since the light went back off.
 
I went to leave today and I had not driven the Jeep in a week. I found my passenger door open and a light left and it barely cranked over. It sounded like a really dead battery. By a miracle it started.
 
The idle is very slow. It died once at a red light. I went to a parts store and saw a man in the parking lot. I told him my story. He crawled under and said there were no loose wires on my sensors.
 
I feel like this is my fault because I did not go to the garage when the light went on, but I could not see paying him to tell me what was wrong when the Jeep was telling me what was wrong. I just wanted the sensor replaced. He wanted to do a whole anaylis. I did not see it that way.
 
So now my beloved Jeep is running like crap. I have two long trips to make beginning in two days. My options are not looking so good.
 
Will it hurt to run it like this until next week? Do you think it will leave me? I am thinking it could be the converter.
 
I am sorry for such long details and I appreciate any advice.

I have a Jeep Cherokee sport 1993 346K miles, out of the blue I went to start it after just driving it, ideled about 2K then just kept stalling. I changed the fuel filter and still the same issue. Checked fuses. I can hear the fuel pump turn on when you turn the key.???????????? Did a fuel pressure check and upon turning the key it was I think around 30 and then it just started dropping, after it stalled the fuel pump kicks back on and the pressure jumps back up. Any Suggestions???? Please help

O2 sensor maybe? Whatever the problem is, I am impressed by the 346K number!

Yes, it runs like a top normally, the only thing I have ever changed on this is the fuel filter a couple of years ago and an alternator. Starting to rust now live in Michigan. Where and what is the O2 sensor???? Thanks, Jeff

JEEP CHEROKEE starts then stalls by sarge836

have a 93 Jeep Cherokee Sport, was running fine then went to start it and it fired up then stalled out chugging etc. Changed fuel filter. I can hear the fuel pump kick on each time, when it stalls I also hear the fuel pump kick back on automatically. Did a fuel pressure test and it drops after start up and then kick backs up after it stalls.
Please help with any suggestions you may have. Great jeep for 346K miles

Sounds like either a IAC (Idle Air Control) switch might be sticking. I'd also check hot and cold fuel pressure. Sometimes if theres a weak fuel pump it will pump fine while warm but if the pump is cold and the fuel pump vanes are shrunken(as everything swells when warm) your pump pressure will drop if the pump is worn. I'd also check pressure before and after the fuel filter. Another thing; if the cold start circuit for the injection is getting bad readings( O2 sensor old and worn, coolant temp sensor worn or air in the coolant system causing air pockets) you may not be able to get the thing to fire due to a lean condition.
 
Just a thought.
