Jeep - Cherokee :: 1998 - Intermittent Cold Starting / Carburetor System With Choke Sticking
Feb 3, 2011
I 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.

It 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.

My 1996 Jeep Cherokee A/C system pushes cold air but out of the defroster vents not the A/C vents. Why this is happening? I suspect it is the slide switches for the A/C system but I am not sure and do not want to take the dash apart before I have some confirmation. I have checked the vacuum hoses with the heater/A/C system and they seem fine.

I have had my 06 for 4 months now. I started to get a cold running problem now that the temperature is falling below 40. When I start it in the morning I wait till the idle comes down before driving. I start driving and it runs rough as if it had a choke stuck closed. I spoke with the dealer and he told me to run lower octane in the winter. That has not worked.

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.

My 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.?

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?

I 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.

I 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.

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 have a 95 Jeep Cherokee that has a strange electrical problem. When I first turn the car on after it has been sitting for several hours, the following accessories do not work:- Air conditioner/Ventilation- Wipers- Cigarette lighter
There are two really odd things going on here: The first is that the radio will not work if any of the above three things are turned on, but it WILL work if they are all turned off. For example, with the wipers and AC off, and cell charger unplugged from the lighter, the radio will turn on. As soon as I plug the charger in, or turn on the wipers or AC, the radio goes off. None of these accessories actually turn on, but simply being putting them in the "on" position kills the radio until they are switched off.
The second weird thing is that after a few minutes of driving, everything will return to working as normal - radio, AC, lighter, etc. They continue to work until the next time the car has been sitting for several hours, at which point the same problem repeats.
FYI, I recently replaced the alternator to address an unrelated issue, but it did not make a difference with this one.
I searched the car talk forums for similar issues, but did not have any luck - while it does look like there are some other Chrysler vehicles that have electrical problems, I couldn't find anything dealing with an intermittent problem.

Pretty soon this thing's gonna have ALL new parts and STILL running rough! The Jeep has about 40K on a Jasper motor, 175K on everything else. I was experiencing starting issues (crank for 20-30 seconds), and noticed a P0171 code on my odometer (O2 sensor?) so off to my mechanic. He replaced two O2 sensors, no change. New code read MAP sensor, replaced, no change.
Finally, changed Fuel Pump in tank (Fuel filter was changed 2 months ago), still no change. I tried starting it tonight by turning the key 5-10 sec. to prime gas, started but still rough at idle. Runs strong above idle 1500-2000RPM. Mechanic can't check fuel pressure at rails? for some reason. My next thoughts were spark plugs and vacuum lines...

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.)

I 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.

My 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.

I have a 1999 Jeep Cherokee and the air conditioner is giving me some problems. The issue is that at random times, it stops cooling, and just blows hot air. Sometimes I can drive all day, and it's fine. Other times, it only blows cold for a few minutes, before the air gets warm.
I've started checking under the hood when this happens, and the compressor is not engaged. I noticed a couple of times that the hoses were frosted over (not every time when the compressor was out). I have found that when the air starts blowing cold, I can turn on the heater for a few minutes, and then when I turn the A/C back on, it will blow cold air again. However, often times the cold air will only last around 10 minutes before it blows warm again. Plus, there are a couple of instances where the heater trick didn't really work.

This problem is from last winter. 95 Jeep Cherokee. After about -10 it just doesn't produce much heat. Heater fan works fine. Jeep runs plenty warm..but what i neglected to mention and or forgot to consider is... I have a tiny leak in the cooling system somewhere. I added just a small amount of coolant a couple of times over the summer and have witnessed a small amount of steam (not lately for whatever reason) coming from the front of engine compartment. I can't find the leak. My question is :Could this cause enough loss of pressure to affect the cabin heating system.....

In the really cold weather after I start my Jeep and it goes in Drive and it's driven for several miles when I go to put it back into Park the shifter gets hung up. It will go into all of the other gears except for Park. If I wait a while it goes back in but it can still feel like it's not smooth.

For three years now my 2001 Jeep Grand Cherokee Laredo will whistle. Usually when the engine is cold. When the vehicle is idling in the driveway or at stoplights, whenever I take my foot off the accelerator it will whistle too. The only time it won't whistle is when the gas pedal is being pressed. I've had it to a number of different shops to be serviced but once the car is inside or the engine is warmed it will never whistle for the mechanic looking at the vehicle. I've been told that it could be related to the IAC motor.

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.

My Jeep makes a whistling noise in cool/cold weather (~60 degrees and below) that no mechanic has been able to diagnose let alone fix the problem. Here are the details...
-high pitched whistling (can be heard inside and outside the car - very loud) only when temps are about 60 degrees and below-after 5 minutes of the car running-only when RPMs are about 2.0 or below.
However, RPMs can be higher when it is colder out and it will still make the noise-as you push on the accelerator, the noise gradually decreases until RPMs are high enough to completely stop the noise.
When temps are around 50-60 degrees, sometimes the whistling will stop after the car has been at a complete stop for about 1-2 minutes-If you turn off the car and let it sit for 1-2 minutes, then turn it back on, usually the whistling will be gone. It will need to sit in the off position for longer the colder the temps are. This problem has been ongoing for about 4 years.
