I am sick and tired of working on my Jeep and not getting any results. I am about to just part it out and try to recoup some of my money. It's an '89 Cherokee 4.0l with a 5spd. Here's the story:
When I bought the Jeep it ran and drove, kind of. I had to replace the slave and master cylinder but it still ran. When that was done I drove it around for a bit without any issues. I got through most of a tank of gas when it started acting up. While at idle something would happen and I wouldn't be able to accelerate. It would just pop and spit and wouldn't go over about 1k rpms. I originally thought it was a clogged fuel filter because the jeep sat for a while before I bought it and sat some more while I worked on the tranny. I replaced the filter,put some more gas in it and drove it home fine. But then it happened again. Now I'm thinking there most be a bunch of crap in the tank so I replace the filter again and drive it home fine. And there it sat for a while. It seemed to only die after driving for a while in city traffic so it was always hot when it happened. There is no temp gauge on my cluster so I don't know if it was overheating or not. My plan was to use the Jeep for road trips so I decieded to go ahead and tear it down and do some major service on it and hopefully I would fix this other problem while I was at it. Here is what all I have done:
Had gas tank cleaned
New fuel pump
New fuel filter
New headgasket and all other gaskets
New distributer cap and rotor
New plugs and wires
New thermostat
All new hoses
New belt
New sensors: TPS, MAP, O2, Coolant switch and temp sensor
CPS checks out okay as well as MAT
Replaced coil with used one
Swapped out injectors with used ones
Fuel pressure checks out
Swapped out fuel pressure regulator with used one
Replaced ground wires
Compression checks out
Oil and filter change
New battery
Checked for and fixed any vaccum leaks
EGR does not seem to be stuck
The plug on the #3 cylinder has oil on the threads. A few others have some as well but it is very minimal.
I think that's about it. Now the problem is bad enough that it does it on a cold engine. It starts and idles just fine but won't rev over 1k rpms. Please help before I scrap the damn thing. Any help will be greatly appreciated.
thanks,
Brandon
