Question about 1999 Jeep Cherokee 4WD

1 Answer

Weird Missfiring I have a 1999 Cherokee and it ran perfectly until a few days ago. I've been experiencing problems with is missfiring. However, it only happens when i hit a bump or turn left. It acts like it want to die and cuts out when any of these two occurances happen. And it even happens when i have a full tank of gas so I dont believe it is becuase of a low gas level. Any help would be great. Thanks

This is an electrical problem. There is a harness that runs in back of the cylinder head. I've seen this harness get worn and rub against the head when hitting bumps. Check the harness also while the jeep is running try moving harnesses under the hood you might get lucky and find if any wire could be storting out to ground.

My 1999 suburban is missfiring on cylinder one, changed new plug, cap & rotor, wires


You seem to have covered almost everything electrical. That leaves mechanical. Either valves sticking, frozen, or spring, cam broken. Fuel line or injector to that cylinder is the only other item I can think of. Let me know how it works for you.

I would be concerned about sediments in the fuel rail. The fuels we use these days cause a lot of corrosion.

I have a BMW 323I 1999 sedan, and I just got 1188 and 1189 codes faults like 2 weeks ago. Today things went worst and while I was parked giving a phone call ad car runnig idle the engine started to run...


I think that you have an air leak. The fact that you hear it when you press the accelerator rather than when you release the accelerator suggests that it is outside of the throttle valve. Check the rubber boot/elbow that fits on the throttle valve. I just had to replace one on an '04 325 yesterday because the rubber was cracked.

Intermittent problem. Truck ran fine one day and barely ran the next time I started it. Runs incredibly rough like it's missing but not like a consistently missfiring plug but missfiring on all plugs...


Check for sticking idle air control valve and stuck open EGR valve. Both are common causes for very rough engine operation due to fuel-air ratio being too far off. Also check for large vacuum leak such as from rubber hoses connecting PCV valve to intake. Feel around for squishy or oily rubber which would indicate a leaking hole in the rubber hoses.

2001 Kia Magentis engine missfiring , installed


check new spark plugs for proper gap.
It may have gotten hit when installing it.check coils second for resistance/firing. sometimes one bank will work fine and the other side will misfire-always replace all together or as a unit. Check
engine for compression if problem pre existed
and check for low compression. if 1 cylinder
has 120 psi and two havepsi below 90 you may have
a cracked head or bad head gasket.

Hi.....

The code P0302, Missfiring detacted at cylinder # 2.
The Code P1313, Catalystic Damaged Bank A , due to Missfiring.
The code P1000, Transsmission check Not completed. during test.

OK. The Important of this problem is, Check the Engine compression on the Cylinder 2.
If the compression is GOOD, Maybe you cen solve the problem Making a TUNE-UP.
But if the compression is LOW, You will need to spend Mony to REBUILT THE ENGINE or HEADS.

OK.. The catalystic come Damaged due to the Missfiring, And will need to replace.

The code P1000. You need a transmission compatible scanner to see if there a code on the Trans.

OK... I hope this help on your question


Thank you for use fixya.....
