ok, what next?

[Sticks]

Ok, trying to be short.

The 99 XJ is running, but shifts are a little messy (Transmission control circuit fail). Probably needs to be rebuilt or changed. I thoroughly cleaned the throttle body cause it was recommended to try and solve an intermittent shutting off problem I had. Since then, it hasn't just shut off on its own like it was doing, but I'm wondering if I should change both o2 sensors. I have a vehicle once that wouldn't run when you first started it cause the o2 sensor was messed up.

Any ideas?

[ex-tbd85hilux]

So if I read you right it's shifting sloppy and doesn't stall out now after starting? But you have a electrical problem with the tranny? Unless I'm more tired then I think I'm not sure changing the O2 sensors are going to help with the tranny issue and if it's not stalling what are you trying to fix?

Sorry Paul. Let me explain a little better.

I have a repeating check engine light produces a tcc code which points to the trans valve body not working electrically. The trans shifts ok, for the most part...but it's noticeable when it does something sloppy...like a tiny buck from a stop. Most of the time, the check engine light is out, but periodically it pops up and then goes out on it's own. The only cure for the tranny is to rebuild or replace. I'm ok with this for now.

Second problem, the XJ was just shutting off intermittently and sometimes would just bog or wouldn't stay running at all. Holding the gas down would keep it running...like you could two-foot drive it. In fact if you held it for a couple minutes, or drove it two footed, eventually it would be ok. I had another vehicle that o2 sensor fixed the issue. I bought both o2 sensors, but someone recommended that I clean the throttle body and the valve thing on the front of it. It was really junky and I cleaned the whole thing. It is running better and hasn't intermittently shut off, but still runs a little rough. I am not trying to to break the bank on changing both o2 sensors, but if it cures the bog than I'll change em'. I guess I'm just being apprehensive about needlessly changing them.

Also, I'm kind of fed up with this silly Jeep. Between window motors, trans issues, running issues...I'm ready to rid myself of it.

WAnt to sell? Willing to buy!!
KEn

Looking for a good solid XJ to lift and use as a DD. My 89 probably won't pass inspection in October.

[Sticks]

I'm always willing to sell, if the price is right. I'm pretty sure I've got the stalling thing cured and I'm probably going to change the o2 sensor just so I know they're new.

[ex-tbd85hilux]

Another thing depending on mileage and year would be the injectors might be clogged. I'm having similar issues with my 97 TJ right now and I'm postponing replacement until after I get the Jeep inspected so that I know what else is going to need to be replaced. I'm popping a p0201 code which leads to the #1 injector being bad. I've ran some injector cleaner thru it but I haven't had a chance to put some miles on it to really clean it out. Maybe next week after inspection.

Karla's been driving it most of today and it hasn't been shutting off or running bad. The AC still is kaput so I'm on the search for a ac compressor....

[87B2XLT]

Andy, read my reply in the wanted thread. I would diagnose with a gauge manifold / meter to see if it's something easier than doing a compressor replacement. If you have access to a vacuum and purge tank, that would even be better. I would vote for a bad sensor or compressor clutch vice the compressor being completely bad. Unless you've already diagnosed it to be low on the high side with a full charge.

Dave - I'm not so good with troubleshooting the AC thing, so "Minekey" did the diagnosis and charged me $85 saying the presssure was low. Which, I am ok with. They didn't see that it was working cause it's part of the symptom...working for a few miles than quitting. I'm not sure what else they did to see what was wrong, but he came back and said that the clutch was probably going bad and that he doesn't believe you can just rebuild the compressor/clutch assembly anymore. He didn't try and sell me anything more...not even the work to make it right...I guess he figured I'd just change it myself.

So, I hear what your saying, but have no idea what you're talking about...just out of my league as a shadetree mechanic.

the way he described it was that the compressor would cycle three or four times, but eventually, it wouldn't engage anymore. He said he touched "something" with a screwdriver on the back of the compressor and "bing" it worked again till it eventually got hung up again.

[87B2XLT]

Andy, that surprises me that they didn't want to 'make some money'. How quickly do you need it fixed? I should be in Hampton Roads next week - Tues/Wed - and I can bring my gauges with me. Will already have all my other tools with me for just in case of issues on the road. I'd have to find some info on what else I'd need as far as testing the pressure sensors, etc., but it shouldn't be that difficult to figure out. You could call Advance, etc. to see if they sell just the compressor clutch, if it's needed. What sounds like might be happening is the refrigerant/oil charge is low and the compressor is freezing up because of it. May have caused the clutch to wear prematurely. Mind you, I'm no ASE certified auto a/c tech, but I've learned a few things over the years Just let me know and I can probably swing by if there's enough room to park the Chevy and a 16ft tag at your place.

Dave G

[Sticks]

I haven't had the chance to even look at who might sell the clutch. I am wicked busy and if you were able to check out the Cherokee, it would have to be during the day and I can't promise that I'd be home. If you're in town and you'd like to take a look, give me a call when you are planning on being available and maybe I or Karla can be around and you can check it out. 7574770799.

[87B2XLT]

Just got to VB this morning. Not sure if I'm up to rowing around the Chevy and trailer much, other than to go to the storage unit and back to the hotel. I can give you a shout when I wake up from my nap and we can figure something out.

Dave G

[87B2XLT]

OOPS. I completely forgot to call you. By the time everything was loaded and I got back to the hotel, I was beat. I was more involved the following morning with getting my storage unit closed out the following morning to even think of calling you, Andy. My apologies. I'm wondering if anyone else might have some insight or can lend a hand....

Dave G

[Sticks]

it's all good brother. Weather has been kind and I haven't really had time to get too involved in it. Thanks anyways...

[87B2XLT]

Well, I generally don't flake out like that, and I kinda feel bad for not letting you know sooner. If I make it back out that way before you get it fixed, maybe we can hook up on it then. I've come to a conclusion that a lot of mechanics out East aren't very good. "We can't guarantee that it's the head(s) or the gaskets"..... yeah, found out what I was expecting on my '89 B2... heads were cracked all to hell from previous repairs failing miserably. It's got new heads on it and is doing well so far. Just got to do the shakedown and all and it should be good to go.
