Maybe it was the threat of violence (or the three cans of gas treatment) but my Jeep now denies ever having a starting problem. I made about 10 laps around the block, then three trips of about 10-20 miles each, then I threw it in 4WD-LO and took it down in the sand pits. Not the slightest...

I would agree on the thermostat issue. My '00 Sport runs 210* whether I'm driving through a snow storm in OH or I'm stuck in traffic down here in FL. If you think its your bearings or brakes dragging, then something has to be making some heat to slow you down. After a good drive on the...

Yep, more thank likely the U-joints. I drove my Toyota through some deep water and (shame on me) did not grease the joints afterwards. Took about six months and the rust just chews up the needle bearings. It could also be wear on the ring and pinion, but that seems unlikely for a '98, unless...

So... you changed your oil, then you added the Seafoam, then the ticking started? How much Seafoam did you put in?

Well, in my case, its just the engine that dies. Everything else still works. Its cut out while (1) sitting in the driveway idling, (2) driving down a dirt road at 10 mph, and (3) drive down the highway at 50 mph. Something seems to be tripping the ECU and causing it to kill the engine...

I was going to drain the tank (on my 2000 XJ Sport) before I pulled it, but couldn't get the siphon hose to go in, so there might be some sort of screen or grid built in. Since I had a full tank to deal with, I went down to Harbor Freight and got a motorcycle/ATV jack for $60. Worked like a...

Every few oil changes, I would add about 4 oz of Berryman B12 Chemtool and about 8 oz of Marvel Mystery Oil to the old oil, idle for five minutes, then change the oil. Usually ran Castrol or Quaker State. My '89 Toyota truck had 190,000 miles on it and the valvetrain looked good as Day 1. The...

OK - I went to Advance Auto and dropped $40 on the fuel pressure gauge. The beast decided to start and I got 48 psi at idle. In fact, it kept a fairly steady 48 psi as I revved the engine. I hooked up the scanner and waited and waited.... and the d*** thing ran 90 minutes without a hiccup...

I had a similar condition on my '00 Sport - vibration would come on around 50mph and go away around 60mph. Felt like a side-to-side shimmy. I had new tires put on, front end alignment, checked and greased all the joints myself, and it still shook at the exact same speeds. I finally installed...

Yes - unless everything is balanced/just right, you will get 'some' vibration in the driveline. ( - part of my day job is driveline analysis) If U-joints are worn, you might also hear or feel a 'clunk' whenever you suddenly accelerate or let off the gas. Just get underneath and check them...

While troubleshooting my current "sudden death" syndrome (http://www.naxja.org/forum/showthread.php?t=68356) I noticed that the fuel tank was not pressurizing like it used to. My current driveway anchor is a 2000 Cherokee Sport with 4.0 engine. The fuel tank has the top-mount all-in-one fuel...

OK - so how do I tell if that is what's happening? Right now, the Jeep is deciding that it will start up and I have an OBD-II code scanner (Actron CP9145 Super AutoScanner) which also shows real-time data. What can I be looking for? When it does quit, there is no check-engine light and no...

langer1 - how do I measure WOT signal? I've got a multi-meter but no manual. When it finally did decide to run, I disconnected the throttle position sensor and it kept running (and gave error codes). I don't even touch the throttle while starting because its fuel injection. Like I said, I...

mattmankow - I'm trying to rig something up so I can check the fuel pressure, but it doesn't seem to be acting like that's the problem. It doesn't slowly cough and sputter, it just dies, and I'm not getting any error codes for lean mixture or the O2 sensors. But I'm going to check... I'm...

Bowzer - no, the battery is fine - I could probably crank the engine for five minutes straight. But, just to be sure, I topped off all the cells and cleaned the terminals. No change. Langer1 - I don't have a "fuel pressure gauge" or anything else that fits the fuel rail port - I'll have to...
