this happened: IMPORTANT NOTE: With the Key OFF, and using the positive (red) lead of your ohmmeter, probe the B terminal of the flat 3 wire connector of the TPS. The letters are embossed on the connector itself. Touch the black lead of your meter to the negative battery post. Wiggle the wiring harness where it parallels the valve cover and also over near the MAP sensor on the firewall. If you see more than 1 ohm of resistance, or fluctuation in your ohms reading, some modifications to the sensor ground harness will be necessary. The harness repair must be performed before proceeding. I can provide an instruction sheet for that if needed. what modifications will be needed to be done to the sensor ground harness thanks!

so finally had time to finish it thanks for that size i needed thanks cruiser but i did the tps test today and its reading a very large amount of ohms anywhere from 10 to 60 so can you provide the instruction sheet for that i didn't see it under your write ups

so i think its a stud with a washer looking thing in front of the oil dipstick tube bracket and the ground wires behind the so called washer but the washer is definitely not movable so should i try the double nut method to remove the stud? do i need to take any precaution in particular when removing the stud? Thanks

hey cruiser i went to check the ground on my dispstick stud and they are all idk how to describe it but behind the bolt how can i take that bolt out and properly clean the area, do you think the PO might have done that area already.

ill do that list and well the stalling is more of like a once a week thing so it is hard to tell but the idle problem still persists although that c101 really needed it wow your right about that nasty gunk getting hard. i have a question though what do you mean by connector refreshing like all my sensor connectors or just the relay panel on the passenger fender?

will check manifold bolts tomorrow as wells as tps voltage but i only had a lil time today so i cleaned the tb iac and the c101 connector. if i have time i plan on updating all my grounds as well. cruiser's write up's just seem like the most necessary tune up these 25 year old trucks need. also any ideas on the random stalling every once in a while? do you think it may be related to the high idle?

i am very familiar with cruiser54's electrical write ups and will begin going through every single one once school ends this thursday. I bought this jeep so i could learn about cars and i've come a long ways imo but love working on my jeep. comancheclub is definitely the best forum site ever and i just wanna kinda get a list together of what to check cuz i'll have lots of time after this thursday

so i have an 87 manche 4.0 4wd with nv3550 that has been fairly reliable but has a high idle problem. when i first start it up it is good at only 1000 rpm but as it warms up the idle will drop down to 400-500 a few times until its finished warming up then it remains at 1000 constant. However once i begin to drive the idle at a stoplight is typically around 1600 way too high. Also i don't know if its related but it will occassionally stall on me but I have made no relations as to what happens the stalling seems to be a very random and intermittent problem. Any thoughts on what should be tested or what direction to move in first?
