So last night I went through allot. I checked and cleaned all the sensor connection. I took out the battery and cleaned the terminals, all the connections both at the battery and at the places where they bolt to the jeep for ground. Checked the cap & rotor ( they looked great ). Took out all 6 plugs, looked great. I cleaned them re-gapped them and put-um back. Then I checked the CPS wire and CPS. The wire looked fine, the unit was tight bolted to the trans.
While messing around with the wire I noticed the MAP sensor tube was not all the way on ( the firewall connection ). Not only was it not all the way on, but the tube was clogged with crap. I replaced the cheap jeep plastic tube for rubber. After cleaning it out and re installing it, jeep started right up. Seemed to run great, never died or stalled. Now im not saying this was the problem on the trail, but it did make a difference after I cleaned it and hooked it back up.
Old Man, the one I have on the jeep is a factory. It started factory, then I swapped it out a year or so ago when I lost all power ( it was a bad coil ) then on the hwy 97, I swapped the CPS again. And again it was the coil. With the MAP sensor un hooked the motor ran like crap then just died, so maybe on the trail it was just barley hanging on, and that why it died randomly.
