I've a 1998 Jeep Cherokee SE 4.0In the morning when it's cold the motor sounds like it's in high rev but the jeep isn't really moving all that fast - just more noise than speed. After it warms up it has plenty of pep and can leave rubber. What is the problem with it?
View 10 RepliesMy 2001 jeep cherokee sport had a transfer case boot replaced a few months ago where the "oil spinner?" is near the rear portion. Before that went out i had periodic noise that i narrowed down to the transfer case using a mechanics stethoscope. Now i have a cluncking noise with gear grinding sounds periodically between 15-35 mph. I have annecdotal evidence from another forum that it may be the oil pump in the transfere case related to a TSB, yet i cannot find this TSB. Am i on the right track? It appears that i can get an oil pump for $60 but i have to consider dropping the case myself and pulling it apart.
View 3 RepliesMy 98 cherokee sport(xj) 190k has always been reliable but now its hard to start. I must press on the gas pedal and rev it up so it doesn't die. Never has done this, after a few revs it seems find. Is my fuel pump bad.?
View 2 RepliesI bought a 1998 Jeep Grand Cherokee Laredo about 3-4 months ago. One problem i have is that the heat wont switch from the floor. I've heard the motor that does this is called the mode actuator, which moves a flap to direct air to different ducts, etc. I've checked all vacuum line that i could see, nothing. It is quite hard to work on as everything is literally jammed under the dash. It is also quite dangerous as I cannot defrost my windshield in the winter. I get a tiny bit of heat up to the defroster, but not a lot. Heat works very well, but cannot switch from floor. Cant even hear the little hiss that you get on other cars when you switch. I just have the basic 3 knob fan speed, directional flow, and temp knobs, as well as an A/C button.
View 6 RepliesI have a 1998 Jeep Cherokee with a straight 6. Lately I have been having trouble with hesitation when I accelerate. It happens at all speeds. It is a stick shift, and as I push in the clutch pedal, the engine races a bit and then as a let it out the car hesitates and/or bucks if I don't give it a shit load of gas. Also, if I let off the gas completely and then try to accelerate quickly it will pause and buck unless I do it really gradually. This problem is intermittent, so I am thinking it might be something with a sensor. Also, if it stalls out completely, restarting the car requires me to hold the gas to the floor. I have already replaced the camshaft and throttle position sensors. Not sure what the deal is.
View 1 Replies I have a 98 Jeep and the cruise control is not working. The light does not come on when I hit the switch either.
I'm reading that it could be the brake switch, the on/off switch or maybe the clockspring. Is there somewhere I can get the voltages that should be at these switches or maybe the ohms for them before I go buy new ones?
I'm driving to Colorado for a week of 4 wheeling and it would be nice to have the cruise control working!
I've got a 1998 Jeep Cherokee Sport 4x4, 4.0 L I6, automatic, 169k miles, that often cranks but doesn't start up. When I cut the power and try again, it starts up right away. I'm concerned this workaround will one day not work and I'll be left stranded, so I'd like to fix this if it's cheap and easy. The symptoms suggest either a lack of fuel or lack of spark due to an electrical problem, so I replaced the ASD (auto shutdown) and Fuel Pump relays, but they made no difference. The other two relays - Starter and Cooling Fan - seemed irrelevant. What this could be? Maybe the crank angle sensor? (I'm not even sure where that's located.)
View 4 RepliesI have a '98 Jeep Cherokee Sport 4Door, 4WD, 5-Speed Manual Trans, 4.0L Inline 6 cyl. mileage: 220,000+At highway speed if I hit a bump the car will start to shake like to fall apart. The only thing that stops the shaking is to ease of on the gas and it slowly subsides. What is causing this? Suspension? Transmission? Steering? Incidentally, the steering is not specifically affected, other than the fact that the whole car is shaking like a jack-hammer.
View 12 RepliesMy Jeep will not start. I can put the keys in the ignition and try to start it and nothing will happen. No sounds, clicking, nothing. The battery is fine, I replaced it with a new one, made sure it was charged and nothing happens when I try to crank it. The interior lights dont come on when I open the door but if i turn them on, they come on but they are very dim. Automatics locks dont work, horn doesnt work. I tried to jump start it with the new battery in with my other car. It tried to turn over but wont come on. It just sounds like the battery is dead when I try to turn it over. The vehicle in question is a 98 Jeep Grand Cherokee Laredo.
View 5 RepliesIt works great for the first 5 minutes and gets icebox cold. I can almost see my breath then the system starts blowing warm air and stays that way. I've had the coolant recharged and the shop tells me there is nothing wrong with it. Of course it works for them.
View 2 RepliesI have a 98 Grand Cherokee (V-8) with 127K on it, that sometimes during cold starts acts like an old carburetor system with the choke sticking. It floods, chokes, it sputters, and you have to maintain an RPM of about 2000 to keep it running and get it to snap out of it. A local shop did a tune up on it before this problem started to happen intermittently, aside from this, it seems to run well. I took it back to the shop and they did several diagnostic tests and even got it to do it for them while they had it.
I told them that it seemed like if we released the key from the start position as soon as it began to fire, the problem would happen, if we held it I the start for a bit longer we could usually avoid it. They returned it to me saying that "Yup, if you hold the start position longer it won't happen, and by the way here is a bill for $103." With the recent below zero temps, it's getting worse, almost unavoidable. My wife says it uses a lot of fuel when this is happening but we have not actually tracked the mileage. Other than this it's a great car but I'm ready to drive it off a high mountain cliff.
1998 Jeep Cherokee sport ... My mechanic tells me that my #1 fuel injector is always spraying and that that is why the jeep runs rough. This is after he already told me that my injectors were clogged and needed to be replaced (which he did). When the car is idling for a while, the exhaust really begins to smell like gas, so this seems to make some sense to me, unlike his previous diagnosis. But now he is telling me that I need to replace the computer to fix this problem.
View 8 RepliesMy '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.
I have a 1999 Jeep Grand Cherokee which I bought used. Last oil change they told me that the power steering pump was leaking. The leak was not enough to be seen, but it did seem to make some noise every once in a while so I took it in to get a new power steering pump at the dealer. Two days after they put the new pump in, power steering fluid was pouring out on the driveway, it was a really big puddle of fluid. I had to put new fluid in to drive it five miles back to the dealer. They said that it needed a new line, they were not sure why it needed a new line, they guessed because of the high mileage, 164,000 miles.
I told them that my Mercury has 287,000 miles on it and has never had the power steering pump replaced or the line either. I have driven most every car I ever owned 300,000 miles and have never replaced a power steering pump or line. But anyway, when the Jeep was supposed to be ready, they told me that the new line blew up spraying fluid all over the shop as soon as they started the Jeep and they had to get new parts so it would take another day or two. My question is what caused the new line to blow? My thinking is there must have been something wrong with the new pump or with the installation, somehow it was outputting too much pressure, anything that could blow a new line, would blow the old line.
I have a 2004 Jeep Cherokee and the passenger window recently popped open. Something is wrong with the power windows (I can't shut it either automatically, or manually).
View 1 RepliesBrooklyn mechanic says "every Jeep Cherokee 2000 6 cyl. 4x4 has this problem--number 3 cylinder mis-fires because it can get too hot". When I return from the country to the city, unload Jeep at the apartment, then, after about 15 minutes, re-start Jeep, it bucks and rumbles and misfires with no power from motor. I pump the gas pedal, and after about a minute it settles down.
Country mechanic has done smoke tests, looked all over for any compression leak, replaced gas cap, put insulation tape over #3 cylinder, and reported that this problem is in the "data bank" of Cherokee problems, where ever that data bank is. The question is, can one live with this problem, or will it cause more problems? Why does the motor settle down after pumping the gas pedal for about a minute? I've had the starter coil replaced recently, as I was told it can get fried from too much mis-firing.
We were flagged down on the highway by a very nice fellow motorist because we were gushing coolant. It was gushing. My passenger was a guy friend who used to work as an aircraft mechanic and works on his own vehicles, so I deferred to his supposedly greater automotive knowledge when he said I didn't need to call a tow truck. We got to within 100 feet of my mechanic (about 5 miles away) when my poor Jeep conked out after losing power and making an increasingly loud clunking noise for the last 500 or so feet. We pushed it in to the auto repair bay. The engine was smoking and would not start. The mechanic replaced a worn out radiator hose, which had become disconnected from the radiator (due to swelling, I think he said?), and the truck runs. There isn't a discernible difference in the engine performance after driving it around town for the day. My question is this: is the engine likely to be FUBAR and am I just playing a waiting game until it croaks?

View 1 RepliesI drive a '98 Jeep Grand Cherokee Laredo, 6 cyl. engine, ~130k miles. I noted a slow loss of power steering fluid a while back and, after hillbillying it for a while (money was tight, and there was a sale on gallon jugs of PS fluid), I decided to address this problem properly and fix it. I added UV indicator dye to the PS reservoir and drove around for several days, hoping to pinpoint the leak. Well, what I found was wherever the fluid is leaking from, it's in a position to be blown by the radiator fan, turning the inside of my engine into an ultraviolet Jackson Pollock painting. (That, or I really am leaking power steering fluid from my #1 spark plug wire). Any tips on how I can pinpoint this leak?

View 7 RepliesI have had no problems out of my jeep except my check engine light came on and it was a bad 02 Sensor and I was told I didn't need to replace it. Well I was driving down the highway and all of a sudden my jeep died. The radio cut off my air and I put it in neutral and I tried to start it and it would not crank. I coasted in a drive way and it cranked and them died. Now it acts like it wants to start but it wont. Replaced the fuel filter. I am getting fuel to the fuel rail. It will not start with starter fluid. I took the crank sensor off and it replaced it and it still wouldn't crank. My fuel pump makes a whinning sound. My lights come on..My windshield wipers won't. My radio doesn't work and the inside lights well I couldn't get them to go off before I before my vehicle died on me, about 3 weeks before I just took the bulbs out. Would the 02 sensor make it not start?
