I am now jacking this thread, sorry OP.
Ok, so I'm throwing no codes. Jeep barely starts. If it does, I need to hold throttle for a couple minutes, and if I'm driving, I need to keep throttle up or else it stalls.
I took off the distributor cap. Contacts inside where corroded. I scrapped them clean the best I could. Started the Jeep and I need to hold the throttle down for a minute to have it idle normal on its own.
I then wiped clean the ICS. Started Jeep and it still needed throttle, but for about 45seconds.
Wiped clean both the TPS and IAS. Started the Jeep and it was a very low idle, but built back up without me touching the throttle.
I replaced the plugs last fall with some champions. Wires are stock, as far as I know, distributor starter and all sensors are stock, again as far as I know. I will be ordering a new cap since the points were pretty corroded, but any other ideas?

I just figured that since a lot of us had some good thoughts to help him, they might still be subbed to this thread and have an idea for me. No harm meant. Sorry.

Well I have some good news and some bad the good news is Jeep is running good now the bad news is I do not know why all all a sudden it is. Jeep has not missed for 5 days now. The only thing I did just before it started running good was plug and unplug computer I had already replaced coil pak, Tps sensor, cleaned Iac sensor , replaced spark plugs, ohm tested fuel injectors, checked fuel pump pressure, cleaned throttle body and that had made no difference. I hope problem does not come back but sure would have liked to found problem not sure how plugging and unplugging computer solved problem. I want to thank you all for your help and comments it was greatly appreciated for sure and I am printing out your answers and comments for future if it comes back or you will see me back to this thread. Thank You Thank You
