Reply With Quoteupdate,
found a vac line that was leaking and I put some Rislone Transmission stabilizer in as well. took it for a test drive it diffidently shifts better, but I don't know if it fixed the problem. I didn't drive it around all that long.
need help figuring out what's wrong
can you guys help me figure out what's wrong?
here's what it does.
after the engine heats up and been driving for about 45 mins or so the engine starts stalling out, sputtering and not shifting. especially under load like going up a hill or something. Some time the engine even stalls out.
the only way to get it to stop is to shut it off let it sit for about 5 - 10 mins and it goes fine for about another 45 mins or so. it really sucked with it doing this on the way up from VA to NY.
any ideas or suggestions?
basic info
89 YJ auto Tranny 4.2
about 1k miles ago changed the Tranny fluid, filter, changed the oil filter ect.
about 2k ago changed the fuel filter, air filter.
did a spark plug distributor cap / rotar change back in Feb.
thanks guys

Is it throwing any codes?
no clue about codes, hell I didn't know you could get codes off it, and then I wouldn't even begin to know where you could or how to pull them

If your tranny have a vacum operated modulator, It will not shift if there is a leak.
You mention a vacum line leak.

If it has a check engine light it will store codes. I'm not sure if your year does or not. You will probably will have to test drive it for awhile and see if the issue is gone. It sounds like you may have fixed it with the vacuum hose. There may be others so while it is running and see if you hear any sucking sounds.Originally Posted by Grevus
ok no check engine light but the vac line seems to have helped as well I'll have to drive it around some more and report back

The codes are behind the headlights...pull them both and you can read the codes...and since you have them out, replace them with round ones...all your problems will now be solved
Sorry couldn't resist...I think you may have found your problem with the vac line, but two other things to consider. You did transmission fluid and filter a 1,000 miles ago? Could be part of your problem, not sure why, but I read this all the time, "I just had my transmission serviced and now it is not shifting right". As for the stalling and sputtering, I had that with my '88 XJ, 4.0L which ended up being the automatic choke, can't remember if the 4.2L had one or not...
one other thing i found, the chock adjustment screw is missing. That could be a VERY LARGE issue my chock is not well working. carb'd so not auto it's electronic
anyone know where I can pick up an adjustment screw?
