Final update in case anybody's been losing sleep: Throttle kept hanging, so I wound up replacing the entire throttle body with a junkyard unit from Ebay. It came to me with all 3 sensors so now I have extras. It was dirty so I had to clean it up before installing. Now the engine has been...

I replaced the alternator yesterday and now it's getting over 13 V sitting at idle, comfortably above 14 V at normal driving revs. So far the idle has been normal now, I may still have some issue with the throttle body sticking, we'll see. So the picture I have now is the old tired alternator...

Started it up today after trickle charging, and it idled just fine, drove, parked, turned off and restarted, came back home. Once home I left it idling and checked voltage at the battery. With the A/C on at idle it was low (12.5 V), after I turned the A/C off it was still low (12.8 V). Even when...

Yes, mine has just the coil spring wound around the throttle shaft. I wondered if a secondary spring was missing, but I've now seen I can have a bad idle with the throttle completely closed. So this seems like at least a couple overlapping intermittent problems.

The battery is new, unfortunately it's been drained a few times now. The alternator may be suspect, how do I check it? If I could buy a TB for $22 that wouldn't be a tough decision to try it. My feeling is that it's draining just sitting still and turned off though. She didn't drive it very...

Well it's treated me to a couple completely different symptoms over the last week: 1. After a cool start, the idle went up to near 2k, then after a few moments dropped down to about 500 and started hunting back and forth from 500-1000. I stepped on the gas after a bit to try and smooth it out...

I meant to say up front that IAC is a real Mopar part. I understand the IAC controls the idle, but it is only able to do so if the TB closes properly, right? I'll try penetrating oil on the throttle shaft. This is not possible to lube? I'll check the battery cables. My battery tray is...

Hi all, this is the first thread I've posted here. I am a new owner of a 1998 XJ, with about 200k miles but a nearly new engine. It's been fun, and since it's a 22 year old vehicle, there's enough slightly wrong with it to keep me occupied. It has experienced a high idle intermittently since I...

My '98 has a few times killed the battery overnight, and I thought it was because the keyway was worn enough that I had turned it to ACC on accident when removing the key, and gotten out of the Jeep and closed the door quick enough I didn't notice. Not sure whether this helps but I will be...
