Hi, I have an 00 XJ with 250000km on it. I'm down in moab from Canada, and my jeep has started to have some weird issues. quite often when idling or crawling at very low rpms, the tach will drop to below 200RPM, then rev back up to ~750 RPM. Today when doing a slow trail, the jeep would do this except it stalled instead of revving back up. It did this quite a few times. we turned around, and it made the descent terrible since I had to keep one foot on the gas to keep it running and one on the brakes. It has also started sputtering and stalling at higher RPMS now. Before this trip, I just installed a new TPS, so unless the heat got to something I don't know if it is that. I'm not getting any engine codes at all over this.
It seems to happen intermittently when I'm not crawling or idling a lot. but when I'm on the trails it happens all the time. I cleaned the throttle body as well recently. I'm under the impression it might be the IAC but I don't know how to test that, and I don't necessarily want to buy a new one if it won't help.
It also doesn't seem to happen when the jeep is cold. Not idling properly makes rock crawling extremely hard. I'd appreciate any help you have. I won't be able to check back for a day or two since I won't have internet. Please let me know if you have had this problem and what you did to fix it. I don't want to stop jeeping on my vacation because of this! thanks
