Cherokee :: 1998 Jeep Started Shaking When Engine Started - Backfire

My '98 4.0 has 213k on it and the other day I started the engine and the jeep started shaking like crazy. Eventually the engine quit and refused to turn over so I looked under the hood and quickly discovered the problem, a deteriorated rubber elbow on the left manifold. The elbow connects to a threaded breather type valve in the manifold and has a thin piece of black plastic routing to the purge solenoid next to the left fender/air box.

When I removed the rubber elbow from the manifold the engine eventually turned over and idled fine, I then headed to autozone and found replacements of the same diameter, I cut them down a bit to match the length of the originals. Since its been a while I changed the plugs and wires, coil pack along with cap and rotor while I was at it. I replaced one plug and wire at a time to ensure I didn't mix things up, same goes for the cap. Now the jeep seems to take a few more seconds to get started but once it does it idles fine.

Now when I hit the gas hard the jeep will hesitate and then backfire. If I'm smooth on the gas the jeep drives good, whether city or highway. When coming to a stop the jeep will sometimes buck slightly like it wants to cut but doesn't. The backfire sounds like its coming from the air box and oddly enough, my aftermarket radio no longer plays in the accessory position, probably a separate issue. So far there's been no check engine light.

I really need to keep this jeep for a few more months and I would hate to put big money into at this stage.

Cherokee :: 1999 Jeep Sputter And Die Out When Put It In Gear

When cranking, i have to give it gas and rev it til it smooths out. Eventually it will run smoothly. When i throw it in gear, it wants to sputter and die out. If I put in D, i have to give it gas or it dies, but I can only barely touch the gas or it dies out. There is a vacuum leak in brake booster, but ive been told the headgasket could be blown.I want to know if the head gasket could be a problem and if its worth replacing the booster.

Cherokee :: 1999 Jeep Keeps Stalling After About 20 Minutes Of Driving

So i have a 1999 Jeep Grand Cherokee Laredo, 4.7L v8 , it has been running good until as of lately. It has stalled or died on me 3 times, I can usually drive it for about 20 minutes, or travel short distances before it stalls out on me, the stalling is completely random, any speed/RPM. I have read everything under the sun about what could be wrong here, but where to start, have been hearing a lot about new Crankshaft sensors, TPS's , etc...

Jeep - Cherokee :: 1999 - Sputter And Have Trouble Accelerating

1999 Jeep Cherokee Limited, 4.0L, 4WD, I-6, 199,000 Miles Every once in a while, after I start the car and drive maybe 50 feet, the jeep will sputter and have trouble accelerating. I push the gas peddle and it sputters (kind of jerky motion) and doesn?t increase speed. If I remove my foot from the accelerator and press slowly back down (I have to repeat this usually about three times before it works), it ?fixes? itself and drives fine. It only happens shortly after starting and it only occurs occasionally. Nothing in the fuel system has ever been replaced, including the fuel filter (because of its inconvenient location).

Jeep - Cherokee :: 1999 - Running Bad When It Gets To Half A Tank Of Gas

about 2 years ago, my 99 cherokee would start acting up at about 1/4 of a tank of gas...i would hit the throttle and it would lose all power like it wasn't getting any gas, it wouldn't stall out, but as soon as i would let off the throttle it would go back to running normal..... i filled the tank and it ran fine again.... i don't drive it much i've only put maybe 3000 miles on it since then, and now it's doing the same thing at half a tank now.... it even stalled out a couple times while idling..... do i need a fuel pump? a coil maybe? it usually runs great in the mornings when it's cold.... but when it gets hot out in the afternoon it starts doing it, or if its been running for a while....

Jeep - Cherokee :: 1999 - Runs Bad Until Stop Then Fine

My 1999 Jeep Cherokee, 4L inline 6, has a very weird problem. Usually, after starting, it runs well for around 10 seconds, during which time I back up and get ready to leave. Then when I switch to drive, it starts to run poorly, having no acceleration in speed or and very little in engine rpm, until I stop using the brakes. Exactly when the suspension relaxes, the idle returns to normal and it runs perfectly after that.

Sometimes the rough running starts while I'm backing up too. So I don't think it related to the transmission. But all I have to do is completely stop, and then it runs great from then on.

This doesn't happen every time, but probably 60-80% of the time. It's been happening for about 2 months now.

Cherokee :: 1993 4.0 - No Voltage At Coil / Backfire Intermittently

I am having a problem solving a will not start issue with my vehicle. It started running a little rough when stopped, it acted as if was going to stall if it remained in gear. I had to place it in neutral to continue to run. I also noticed a backfire condition that was intermittent sometimes under acceleration. After about three days of this condition now the vehicle will not run. I have checked the fuel pressure and it is within specs.

I found there was no spark @ the spark plugs so I checked the crankshaft position sensor and observed a high value of resistance between terminals B&C therefore I installed a new one. After further checking there is no voltage at the wiring connector that supplies 12V to the coil with the ignition in the on position. I'm not sure what is the correct method in checking for this voltage is. I read that it could possibly be the ASD relay so I tried another matching relay and there was still no voltage at the coil. At this point I am somewhat at a standstill and not sure where to proceed.

Cherokee :: 1999 Jeep Won't Crank Or Make A Noise When Trying To Start

My husbands jeep is driving him crazy. He drove it to work and started fine. Then went to start to come home. Nothing. No crank, no click, nothing. Towed home. Battery OK. Anyway, he put new starter on. Started up. I drove it to station. Got in to come home. Nothing. Same darn thing. We jumped it. Pushed it out of way. Started. It's done this many times. Let me say, though, he went through a huge amount of water before this happened. Gauges went nuts for a while. Don't know if this could've messed up a sensor. He's losing sleep over this.

Jeep - Cherokee :: 1999 - Intermittent Airbag Warning Light

A year ago I replaced radiator, long job in the winter in an unheated garage. After radiator was successfully replaced Air bag warning light started to come on intermittently. More so in cold weather, less so as it warms up. I know you have to be very careful working on air bag system, disconnect the battery and wait 10 minutes. I have heard that this is a known problem on Jeeps, this is a 1999 Grand Cherokee with 150,000 miles. I think ti ha something to do with connector in a dash, what can I do, a car is on its last legs, will not spend money on a dealer to fix, ripped off too often during life of car. I am afraid it will not pass an Ill environmental test (not related to pollution control) I suspect it is setting a trouble code but have not checked as of yet, hasn't warmed up in Illinois yet this year.

Jeep - Cherokee :: 1999 - Lurching And Stalling 1 To 3 Times Per Week?

I have a 1999 Jeep Cherokee Sport, 4.0L (6 cylinder) that has 128,000 miles on it. Within the last two months it has started lurching 1 to 3 times per week. It only lurches once but always when the engine is hot and when accelerating. The engine light does not come on. It also loses power for several seconds at other times. Lastly, it has stalled two times in three weeks when I am coming to a stop. The spark plugs and air filter were changed last week. The injectors were also cleaned.

I do not have the skills to fix it and am taking it to the dealership which is very expensive - thus the money drain. Any thoughts on what might be going on? Or is it better to just cut my losses and look for another car. I would really like to keep this car for another year because I am in graduate school but am not willing to continue with the money drain.

Jeep - Cherokee :: 1999 - Oil Gauge On Instrument Panel Is Pegged Fully To The Right When Stopped

The Oil Gauge on the Instrument panel of my '99 Jeep Cherokee Classic is pegged fully to the right (TWICE the normal reading) when the vehicle is Stopped at a Light or stop sign. As I accelerate the needle drops down to NEARLY normal but pegs again as I decelerate to a stop. The engine sounds normal, operates like normal, no smells, oil level on dipstick is OK. What's up with this?

Jeep - Cherokee :: 1999 - Hesitates After Start And AC Stops Blowing After Hour Driving

My jeep is having two issues. First, almost every time I start the vehicle it idles fine, but then when I start to accelerate it bogs down for 1 to 2 seconds. I will accelerate through it and after that it runs fine and doesn't do it again until the next time I start the vehicle. My second issue is that after driving for a couple of hours with the AC on, the flow of air out of the vents drops. The air is still cold to the touch just barely blowing. Once I cut the motor off for about 30 minutes it works fine again for a couple more hours. Also, when the intensity of the air coming out of the vents dies down the blower motor sounds like it is working harder to put out the little bit of air pressure.

Jeep - Cherokee :: Blinkers Go On And Then Off

2000 Jeep Cherokee Sport: Sometimes the directionals shut off after a few blinks and sometimes they don't work at all. I think I identified the area where the blinker noise comes from. It is to the left underneath the steering wheel column.
