Jeep - Cherokee :: 2001 - Starting After Crank For 20 To 30 Seconds And Idling Rough
Aug 6, 2014
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 am about to begin servicing my new/old jeep. I am unfamiliar with fuel inj.
it is beginning to run a bit rough idling in drive with brake applied. It is beginning to start less easily, turning over longer before firing...

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.

After I start up and drive my jeep around town and then shut the engin off. Then I get back inside the jeep, start it up the engin idels rough. Some times the engin light comes on. I had a coil pack installed and still the same symptoms. What do you think?

I have an '89 Jeep Cherokee and it idles way to high. In park it idles at from 1500-3000 after being warmed up. In drive it idles at 1300-1500. It idles at 2000 at 35 mph. We've replaced the O2 censor, the throttle positioning censor, the coolant temperature sensor, and a few other parts. None of this worked.

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.

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.

I have recently cleaned my throttle body and still have a rough idle. The rough idle is intermittent and especially occurs when I am in park and then hold on the brake and switch to reverse or forward without pressing the accelerator down and let it sit for a second. When it happens, it is usually so rough it wants to just stall out if I don't give it some gas.

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.

I have a 2009 Jeep Grand Cherokee. Engine is running rough. Check engine light comes on. Code is P0152. The code is defined as high voltage on the front o2 sensor (bank 2). I hooked up the scanner again and checked the voltages. Both O2 sensors on bank 2 are never making it above 0.1V. That seems to contradict what the DTC is telling me. Is that somehow related to the fact that it is not going into closed loop? I'm a little confused.

There was one message that I found like my problem, but a little different. When I turn the key it won't start, just sounds like it is going to start. I turn the key the second time it will usually start. sometimes it takes 3 times.

I own a 2001 Jeep Cherokee with 104,000+ miles. It runs great and doesn't have any issues. However, i started it up this morning and the check engine light came on. Should this be concerning? I haven't done any real maintenance on it since it runs so well. And i guess that's my other question - what should i do to the Jeep to keep it running for another 100,000+ miles? Spark plugs? Timing belt??

About 6 weeks ago I became the proud owner of an '88 240 wagon with ~ 235,000 miles.
When turning the key over to start Lucy (that's her name) most times she will crank for 3 to 5 seconds before indeed starting. I can avoid those 3 to 5 excruciatingly long seconds if I let her crank for a time or two then let her rest for a second - after that she will start up immediately when I turn the key again. This situation happens probably 14 times out of 15. The 15th she will start like a dream the first time. I have had the battery tested (although I could not find a date on the battery and the previous owner did not know when it was purchased), and I have completed a full tune up (plugs, wires, rotor and cap) among other maintenance issues as well.

I have a 2001 Jeep Cherokee Sport edition, automatic transmission, about 100k miles. Recently, when I turn on the engine -- sometimes -- it is very loud, and the car really shakes back and forth (in place) with the engine. It almost feels like the car is going to die. It feels like a very bad idle. If I wait, nothing changes. If I turn the car off, wait, and turn it back on, nothing changes. If I hit the gas, it continues, but decreases very quickly and by the time I hit a stop sign or red light (let's say 100 yards away), the car is more or less fine; no more fear that it's going to die, although there's still some noise that seems like it's coming from somewhere between the transmission and engine. I had the starter replaced last June (when it went kaput) and replaced the idle control valve a couple of months ago (the car kept dying when I came to a complete stop). I mainly drive it to/from work, about 50 miles each way, going 45-80 mph on a hilly freeway, and there have been no problems while driving.

2001 Jeep Cherokee sport ... Just bought this Jeep with 145K miles. Had radiator and all hoses replaced. The overflow tank is boiling over but the engine is not overheating. Safe to drive? What should I be checking for?

I have the 1.8L engine with automatic transmission and when I start my car, it has a loud grinding sound that lasts about 3-5 seconds. The Initial rpm after you start the car also idles around 1800-2200 rpm for almost 10 seconds before it goes back to 1000rpm.
The high idling also stops if you shift it into Drive (D) or Reverse (R) but in Neutral (N) it will jump back up to the high idle.
This started occuring november of last year. At first I took it to dealership but they could not diagnose it because they never heard the sound. It ONLY happened when it was cold below 30 F, but recently it has been becoming MORE and MORE frequent and now almost happens everytime I start the car. But it won't happen if the outdoor temperature is above 60 degrees or if I start the car shortly after I shut the engine off (like a 2-3 hour break in between).
I thought it might be a loose flywheel, bad torque convertor, or a faulty electronic throttle control system. I do NOT think it is the starter because it starts everytime even on the coldest of days just that the grinding sound is annoying.

I have had a Jeep Grand Cherokee for about 4 years. Over the last year or so, I have been having coolant loss. At first, it was very little over the course of a month. Now it is about a half a gallon over a few days. We can't find any leaks. The oil does not appear milky. There is a bit of moisture under the valve cover. What could be the problem?

ODB2 Code: P0300 - Multiple Miss-fire
I have an issue with my Jeep Liberty. It started idling rough with no error codes. about a week later it through the Multiple misfire code. I started by replacing the spark plugs. The old ones were from 20K miles ago and still looked good. Replaced them anyway. I still had the code. I put K44 fuel injector cleaner into the tank and drove it home (2 miles.) The next morning I started it and went in side because I had forgotten something. I came out to extremely thick black smoke. It went away after about 2 minutes, the computer code cleared, and the engine idled perfectly. About 2000 miles later the car is once again idling poorly. I added K44 again and for that tank of gas it ran fine, no code. Once new gas was added it threw the same error code and idles very roughly.
So here are some basic info pieces:
1. 8 tanks of gas from 8 different locations.
2. Adding K44 has shown a direct improvement both times, but more significant the 1st time.
3. New spark plugs
4. New coil packs
5. 2005 Jeep Liberty - 3.7L V6 at 99,872 miles
6. Hopefully unrelated is that the car has a small radiator fluid leak I haven't found. It requires 1/2 gallon every 2K miles or so.
There is no knocking sound, it just sounds like there isn't enough gas. Car responds fine to accelerator. Above 10mph car seems to drive smoothly.

My 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.
