Jeep - Cherokee :: 2000 - Misfires / Check Engine Light Keeps Coming On

I have a 2000, Jeep Cherokee 4.0L. The check engine light, keeps coming on, and the scan tool, shows P0300, P0301, P0302, P0303. Misfires in #1, 2 & 3 cylinder.

I replaced the Coil Pack & all spark plugs with genuine jeep parts from the dealer. What might be wrong or other things to check?

Jeep - Cherokee :: 1993 - Engine Softly Stutters And Misfires While Driving And CEL Came On

My inline 6 engine softly stutters and misfires while driving and has the check engine light on whenever this happens. It's becoming more frequent now - 20% of the time I'm driving I'd say. The codes are 11, 12, 27, 34. I've looked up the meanings of the codes and I'm leaning towards its bad fuel injectors or a bad connector leading to the fuel rail. I have lots of bad wiring on my 93 Cherokee haha. I've fixed so far: a bad head light connector, and an exposed wire that connects to my distributor - it would swing and touch my engine block causing the engine to die.

But now I am struggling on how to fix my small stuttering engine problem. So the problem only occurs after I make a strong left hand turn such as a 90 degree or a uturn so that means a connection is being pulled to the right. It doesn't have an issue turning to the right though. I don't have sway bars on my 6" lift so there's a reasonable amount of body roll to pull on the wires etc. When I open the hood with the engine running smoothly I can touch and wiggle the front fuel injectors and sometimes I hear it softly misfire or sputter. What connectors lead up to the fuel rail?

I live on a boat access only island, so desperate. This jeep has over 230,000 km on it. Runs well, but this year started this thing where it won't start first time crank, but always starts second or third go. Bought new battery last year, so doesn't seem to be that kind of issue.

Jeep - Cherokee :: 2000 Would Not Start / Turn Over Then Die

This past week when I went to leave work my jeep would not start. It would turn over once, and then die....but if I kept my foot on the gas and kept the RPM's up it stayed running. So, I drove it home with one foot on the gas and one on the brake so it wouldn't stall out on the road. The next 2 days the same thing happened when I went to leave work. It starts fine the rest of the time, even first thing in the morning when it's cold..

Jeep - Cherokee :: 2000 - How To Replace Air Compressor

Jeep - Cherokee :: 1989 - Idling Too High / 2000 RPM At 35 Mph

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.

Jeep - Cherokee :: 2000 - At Start Up Stuttering / Alternator Or Starter Won't Working?

I have a 2000 Jeep Cherokee 4.0L with about 180,000 miles on it. I'm currently in the middle of a road trip, and today my car's been stuttering as I've started it up. After the car sits idle for a while, it stutters as I turn the key ("chug-chug-chug-chug-chu-chu-chu-chu-fail" is about how it goes). When I take the keys out and put them in again for another shot, it manages to start on the second or third try.

It runs OK once the engine gets going, and after I've been driving for a while I can turn it off and on again, without any problem. My main questions are: (1) Is this likely an issue with the starter, alternator, or something completely different? and (2) just how serious is it? If I can get the car running can I make it another ~1500 miles, or should I try to find a dealership before making it back home?

Jeep - Cherokee :: 2000 - A/C Blowing Warm Air - Leak At Evaporator Coil?

My wife's 2000 Jeep Cherokee has a failing A/C system. Last year it was blowing warm air in the middle of the summer so I took it to a local mechanic who recharged the freon and it was fine through the rest of the summer. This year it is blowing warm again so we took it in for another recharge and it only lasted a few days. The mechanic said there is a leak at the evaporator coil(?) He said the entire dash needs to be removed to repair and it would run about $1000 to fix. This seems a bit steep. Any thoughts or experience with this issue?

Jeep - Cherokee :: 2000 - Thumping Noise While Accelerate From Dead Stop?

Jeep 2000 Cherokee

So I have this thumping noise, almost sounds like something is loose.The noise occurs for a few seconds when I accelerate from a dead stop and then goes away, it returns when I slow down and almost come to a complete stop.The noise also goes away when I put her into 4wd.The thump/rattle sounds like it is coming from the center counsel area and directly under the floor board in the driver seat.My car changes gears smoothly up and down while driving.

I was told it might be a transfer case problem and that it might need to be rebuilt, which makes me worry.

Jeep - Overheating - Weather - Cherokee - Clutches :: 2000, AC Clutch Won't Engage On Hot Days

2000 Jeep Cherokee Classic 4.0L, in Palo Alto, CA.

My air conditioner clutch stops engaging after driving in hot weather.

In hot weather (>80 degrees), when I first turn on the AC it blows nice and cold for up to 30 minutes, after which it gradually gets warmer and then hot air comes out. If I leave the AC on when it is blowing hot air, it will suddenly blow cold again (sometimes it takes a couple minutes for it to work again, sometimes it takes 30 minutes). Then the cycle repeats.The AC seems to be dependent on outside temperature: on very hot days ~95 degrees the AC will only work for ~5 minutes before blowing hot, 80 degree days the AC works longer, limited testing in cooler weather (at night ~60 degrees) AC always blows cold. When it is blowing hot air, the clutch on the compressor hasn’t engaged. When the AC is blowing cold, the clutch engages/disengages normally depending on how you set the temperature. I replaced the low pressure switch, did not change AC function. I recharged the AC, did not change AC function.Engine temperature reading always in normal range <210 degrees. Heater is working normally.

I’m pretty sure the clutch is getting the signals to engage. When the AC is working normally the engine revs slightly higher when AC clutch is engaged.Likewise, when the AC is blowing hot air and the clutch isn’t engaged the engine revs higher. And if I disconnect either the low or the high pressure switches the engine reduces to normal idling.

Jeep - Cherokee :: 2000 Suddenly Jolts With A Loud Bang When Traveling On Highway At 65 - 70 MPH

I have a 2000 Jeep Cherokee Classic with 214,000 miles on it. Ok......this hasn't happen too often, but scares the CRAP outta me when it does.The other day, it happened twice. Traveling on the highway, 65 - 70 MPH, the car suddenly jolts with a loud BANG!I've had the transmission fluid flushed.Each time I go in for service at my local garage, I have them check ALL the fluids. They never find anything. And are at a loss as to what it could be. They've dropped the pan and found nothing wrong with the transmission. No metal in the fluid. They've check the rear diff. Still nothing. I've gone about a year without the issue until this past Monday when it happened twice. I'm a little paranoid to go faster than 60 - 65 right now.

Jeep - Cherokee :: 2000 - High Pitched Whistling Noise In Cool / Cold Weather

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.
