Problem might be resolved!!!
Dad and I replaced the intake gaskets. They appeared to be leaking and were very very brittle and dried out. 289,000 miles. This absolutely gave more vacuum on the gauge we had hooked up we were at a steady 20 in/Hg no matter how you rev'd or drove the jeep. Now we are getting 22 in/Hg all the time with spikes above that at times depending on how its being driven. Test drive resulted in the jeep no longer pulling its self down the road like it had been doing. It was still reving up on its own in neutral and now was searching between idle and 2500 rpm.
A few days later I started getting Service engine soon light for code P301 which was cyl. #1 misfire. So since I had gotten rid of this code before by rerouting spark plug wires... I started that process again.. Its funny how many people will look at you in a parking lot when you are under the hood but no one will even say hello!!! LOL.
After some rerouting of the spark plug wires (about 10 different tries) the service eng. soon light went out on its own and it appears to no longer misfireing..
SO with that long post... intake vacuume leak fixed
marked improvement. Misfire code back and patched. I dont know if i would call it a fix. Jeep now slows on its own when you let off the gas..
Now for the fun part.. I am wondering if my new parts store spark plug wires are causing me problems with my misfire .. Does anyone have any experience with new non oem plug wires producing too much EMI and messing with the injectors and computer?????
Thanks for all your help.
