| 96 JGC Lmtd with a little over 200,000 miles on original motor. New computer, fuel pump, fuel filter, water pump, battery, Spark plugs & wires,distributer etc. Did all this before my move from Indiana to Gatlinburg, TN. Jeep drove flawlessly down to TN, the next day my wife and I drive it to the store (about 8 miles away) and notice the engine light is on. On the way back from store jeep starts sputtering like the engine isnt getting gas (starving for gas) and dies. The oil prssr gauge would drop and go back up as motor was stalling and check gauges light came on, all other gauges were fine. After letting it sit about 20 mins I was able to start motor and drive it home. Next day same prob.. So I (not a mchnc by any means) installed new O'2 sensors and a new oil sending unit Changed oil to 10w40. Long story short(sorry) now pretty much same prob minus the oil prssr gauge going all the way down and back up the motor still stalls out after I let it idle for about a hour exactly. Just seems like after warming up it starts to sputter really bad like its not getting any gas(even when you give it the gas to try to keep it running! and dies. wait about 10 mins and it starts back up but dies shortly after. Running out of patience and really dont have the money to take to dealership! Can anyone help? | |

Hey folks, I have a 2005 Grand Cherokee with 4.7 liter V8, 2 Wheel Drive, and the Trans will feel like it slips a little and the check engine light comes on and the code shows P0700 and U0513. It will not shift form 4rth into overdrive, any suggestions? Any help will be greatly appreciated.

| I have a 2004 jeep GC Overland. It sounded like it had an exhaust leak and it could not be found It seemed to go away after it heated up. I now have white smoke coming out of the tail pipe but not all of the time. I did a test on the intake manifold with starting fluid but found no evidence of a leak there. Is there any other way for the coolant to reach the exhaust on this model? I have no evidence of leaking from the heater core no leaks in the cooloing system ect..... I am afraid it might have a head gasket going but it still maintains pressure in the radiator. I also get a gargling sound from the under side of the dash board in the passenger side. It sound like standing water and splahes around when I accellerate and go around turns.. This is very puzzling and I do not want to tear into it unless I am sure what the issue is any help would be greatful.1 | |

My truck has been out of commission for a while now. I'm thinking that its my fuel injectors after inspecting several sensors. Here is what my JGC does when i try to turn it on: 1). As I try to turn it on it makes a clicking noise 2). when it does turn on the motor accelerates as if i was stepping on the gas and the RPM shoots up. 3). After a few seconds of (step 2) the RPM drops down as the acceleration decreases dramatically to a point were it wants to turn off. It continues to dance on the RPM scale from 1k RPM to 500 4). When i would step on the gas pedal it wouldn't respond only if i were to press it down several times. but it would come in delay periods in between after i press the pedal. 5).Finally it turns off on its own or when i try to shift it to reverse or drive. It be the obvious thing to take it to the mechanic but money is a lil tight right now so I'm open to any suggestions from anyone out there.

This is a 1989 4wd 2.5l 4-cyl auto 2-door Cherokee. Granted that by design it's not very powerful... But in addition it has a really annoying quirk. When under hard throttle acceleration (what other kind is there with a 2.5l four?), motor doesn't seem to be pulling at full power. But when the throttle is backed off halfway or more, the motor actually "surges" and runs stronger at part-throttle than it does at full throttle. Also occurs in normal driving, just not as obvious. Not a misfire, just weak... For various reasons, over a couple of years, have ended up replacing EGR valve, dist. cap & rotor, wires, plugs, fuel filter, tried swapping fuel pumps, swapped to a different throttle body (& checked correct fuel pressure), replaced O2 sensor, catalyst (loose pieces were rattling around inside), replaced water temp and inlet air sensors, swapped ignition module and MAP sensor at one point or another, bought a new (high-altitude) CPS, etc. Last update was to add a "torquer cam" (great results from that). But still it surges. Took it in to Jeep dealer for analysis -- they "tweaked" the TPS setting, then told me their best guess is that this is caused by "a slow computer" (a $500 replacement based on a guess?). I've been in electronics many yrs; generally you either have a good computer or a dead computer -- a "slow" computer would have to violate numerous laws of physics... (the Renix CPU is like the Eagle; not much in the way of retained error codes or diagnostics to look at) Starts & runs (as well as can be expected), gets good mileage, but the non-linear throttle response is crazy. Any ideas, or anyone seen this on another Jeep? Maybe it's generic to the 4-cyl? |
