89' Jeep Cherokee, 4.0, 4x4
About 3 weeks ago, my Jeep began stalling and surging when I would come to a stop, or slow down and then re-accelerate out of curves. Idle park RPM= 400 Idle InGear RPM=220
Then about 2 weeks ago, I noticed the Idle in park was around 300 RPM's and in gear, 100-150 RPM's. This caused it to die when shifted from park to reverse/drive. If I held the gas enough to get the RPM's up to around 500 or so, it would stay alive. However, there was still that original stalling and surging.
Well, 3 days ago, I hopped into my Jeep and drove off, and noticed that the sputtering/stalling/surging had ceased to exist. Once I had stopped and put in it park, the RPM's went up to 1600. When back in gear, it was down to a little below 1000. This seems way too high, especially the InPark RPM's. This is where it is at right now.
Here's what I've done to the Jeep before and during....................
I used STP engine oil treatment about a month before all of this occured. This caused a bit of a change in oil pressure, like it would stay about 80 until engine warmed up, then it would be 40 @ idle, 60 @ 55mph, 80 @ 75mph...which was normal for my Jeep.
I also originally changed the fuel filter because of the surging, then plugs, wires, distributor cap, rotor, ignition coil(just cuz). All this was changed in the first week of experiencing these problems.
After the second week of these problems, I changed the air filter(wasn't really all that bad) and added some Lucas Oil Fuel System Cleaner to the 20 Gallons in the tank....2 days later, we arrived at the current problem.
anyone that can help, please let me know what you think!
