But at this point I'm willing to check everything that is suggested to figure out what the problem is. I was hoping it was an external problem, not internal. I will check the compression over the weekend and see what it shows. Re: Engine problems! HELP! [Re: KGH1994YJ] #805724 04/22/07 02:35 AM Joined: Apr 2007 Posts: 15 K KGH1994YJ OP Need a Spot I don't doubt that broken rings and busted pistons would be the source of the problem, but wouldn't it be smokin' like a barbecue grill if the rings were bad? Luckily, mine's not smoking at all. I'm plannin' on checking the compression tomorrow. Any thoughts? Re: Engine problems! HELP!

In all honesty, the tired old 4 banger had 145,000 on her, so I wasn't surprised when I found out that she was toast. You can't expect reliabilty out of a 14 year old vehicle!!! My next vehicle will be a Toyota or Ford pickup (we sold WAY less parts for those trucks than any other) or a Honda, umm, Accord? American 4-bangers vibrate the fillings out of your head, i.e. Chevy Cobalts, Saturns, Escorts, Neons. There is NO comparison!!! Re: Engine problems! HELP! [Re: 93yj] #805726 04/23/07 02:14 PM Joined: Apr 2007 Posts: 15 K KGH1994YJ OP Need a Spot My Jeep is not my daily driver, although I do drive it alot. I'm not looking for so much reliability but just dependability. I do want to find the source of this problem so I can go on Jeep rides with my buddies and not worry that it's going to crap out on me. If I had the money to spend freely I'd do a V8 conversion and drop an LS6 or some other hot engine in it. But I'm on a budget like most people are and just trying to fix her in the most economical way possible to keep it running! Re: Engine problems! HELP!

What's the difference between reliability and dependability? 1977 CJ-7, fiberglass body, AMC 360 w/ headers, DUI ignition, Edelbrock intake and Holley 4150 carb, TF999, Dana 300, 4.56 gears lockers, York air comp, 4" susp lift, 2" body lift, BFG 35" M-T tires, Megashifter, AGR pump & box, REP8000 winch.

The Hondas and Saturns he mentioned I would call "reliable" cars, but I expect my Jeep to be "dependable" on the trail, and on the interstate for that matter! Either way I just want it running right. It's now showing code 51 which is "Oxygen sensor, running too lean." I've replaced the O2 sensor and checked the vacuum lines. What else could make it run "too lean?" Re: Engine problems! HELP! [Re: KGH1994YJ] #805729 04/23/07 06:00 PM Joined: Oct 2003 Posts: 7,768 Central Texas BigJim Web Wheeler I would guess running too lean could be a product of the iac or the tps maybe even the cps could be sending the wrong signal to the computer.

I've read alot of articles and posts about this sensor going bad and causing all sorts of problems. Re: Engine problems! HELP! [Re: KGH1994YJ] #805731 04/24/07 11:11 PM Joined: Oct 2003 Posts: 7,768 Central Texas BigJim Web Wheeler Well the cps sits in the hottest most greasy,oily palce unde the hood... It is a simple electric thingy that counts the revs of the camshaft. It doesn't seem to go out more often than other electornic senders under the hood. However when it does go out it is usually a mystery as to what to do to repair the vehicle.
