Once the fuel is injected into the cylinders it gets fired and then it is nothing but exhaust gas.

BUT I still think heat does have something with this problem. I wonder what would happen if the OP pulled his hood or pop it partially open like I mentioned earlier?????

IIRC the one thing the OP didn't do was check for stored codes. Didn't one of us tell him about the 'key thing' for reading any DTC's? OR did he do so and I freakin' forgot already......I gotta get me some brain pills...
I agree heat is what's causing it. Its something worn or carbn build up. He did pull codes I thought.
He said it does it even on cool nights so I think its carbon or a bad pick up in the dizzy. If it was the coil it should miss since the coil fant make it fire off time but the pick up can. It works wirh the crank sensor to determine ignition timing. If the sensors are not accurate the engije computer can't be eithier. If it was crank it shouod lose spark entirely but the pick up can cause weak or miss timed spark. If it is just starting ro go its had readings can be caused once it heats up

Checking the cam pick up on a '95 YJ. Your '93 should be the same:
Got to eliminate things or you will go in circles forever. Wait until it is running bad;

http://home.comcast.net/~laybackman/...ensor_test.pdf

Questions for the OP and this is a shot in the dark. When it happens again what is your speedometer doing? Jumping around a bit? Then if it is unplug the VSS sensor on the transfer case. It is screwed into the transfer case and supplies info to your speedometer. It is on the same 8 volt supply circuit as the crank and O2 sensor. If it begins to fail it causes issues until it shorts out completely and you do not get anything. Again just a long shot.

Nope speedometer is always steady. The problem with checking it when it runs bad is that if I stop on the side of the road for literally 2 minutes, it starts run I g if e again for a few more miles. Then I have to stop again. I'll grab a pickup today when I grab the fuel filter (they didn't have one last night) and slap them on one at a time and see if it helps.

Usually when the VSS start acting up the speedometer can get jumpy since it controls it. At this point the only alternative to testing is to replace the cam sensor.

A fuel filter replacement is mandatory if you do not know when it was changed last.

Good Luck!

One more thing to think about. If the coolant temp sensor is not sending the right value to the ECM you will run like crap also. It is often overlooked as a problem with a warmed up engine problem. I''d swap that out first since it is a lot less expensive.

An easy teat to see if it is vss is to just unplug it. Normally when coolant temp goes it runs like crap all the time. Not just warmed up bit anytging is possible

Ok. I'll check that when I get the driveshaft back in it. Rear of the tcase was leaking so I dove into that. I tried the water in the throttle body trick and it didn't work. Pulled it off and cleaned all the carbon off of it. Intake was pretty nasty too. Cleaned what I could and sprayed the crap out of it. Changed the fuel filter too and no change.

This says you have carbon build up in the cylinders to then. Dont know if its bad enoughto causw this though. I really think its the pick up

This might be it; I would call them first.
But Autozone or Advanced auto parts should have this also
http://www.jeep4x4center.com/distrib...-56027023.html

I do believe that the OEM part number is 53009077 and is called a stator or magnetic pickup.

Ok. Went and ordered the stator today...should be in tomorrow. Got my seal replaced on the tcase out shaft. Need to fix a leak on the front axle as well. Want to tear into it and broke my half inch extension...can't say I've ever done that before. That's thing is on there! Looks like I'm taking the night off
