Ok so I have had it with this hot start problem! :gonnablow
My 2001 4.0 AW4 Cherokee runs great! It starts right up cold. And it starts right up hot.
Be when you let it sit for about 15 min hot, especially on a hot day it srats right up and runs like crap!!!!!!!!!!!!!!!!
I have changed the following parts in the last 1,000 miles.
All O2 sensors with new Bosh.
Spark plugs.
Spark plug boots.
Crank sensor.
Cam sensor.
IAT sensor.
TPS sensor.
IAC unit.
Coil pack. (One used one, one brand new one.)
Oil pressure sensor.
Temp sensor.
Changed the oil and filter.
New air filter.
Sea Foamed it before new plugs.
Ran seafoam in the fuel tank.
It still has this problem.
When its hot and you park it for about 10 to 20 min and then start it back up it runs like crap. Acts like its running on 4 cylinders. Rev it a few times, and or just let it run for a few min and its fine. Clears right up and runs great.
But until it clears up, you can not put it in gear. It will stall. And at times it takes it a few min to clear up.
Today I pumped gas in it and then went in to pay. Had to wait in line. Came back out and I have cars waiting to use the pump behind me. Start the Jeep and it runs like crap. :bs:
Takes it almost a full 2 min to clear up so I can move. People are honking at me, and I feel like a fool.:dunno:
So what is causing this problem?
