How old are your spark plugs and wires? (miles since changed) If wires and plugs are good , it's probably a problem w/ the fuel injectors.

92 jeep cherokee engine cutting out after 30 minutes drive. Random occurrence/highway driving at 45 to 65 MPH. Engine cough/sputtering is dramatic and eventually corrects itself.


Sounds like you may have dirty injectors. Have you tried a good fuel injection cleaner? Lucas is a good product that works. You may have to use it in 2-3 tanks of fuel if the injectors are real dirty.

It would help if you found a shop with a code reader for a 92 Jeep and had them give you the codes. Unfortunately the free code reading service offered by auto parts stores only works on 1996 and later OBDII vehicles. Pre 96 is OBDI, from around 89-95, and requires a different reader or module for each manufacturer. Many shops use a Snap-On reader with different modules, and should have the Jeep module. Cost will vary, but the codes will help diagnose your problem if the injector cleaner doesn't fix it.

2000 Jeep Cherokee Sport I-6. Runs rough at idle sometimes and will go away if you bring rpms up for a little while and then release throttle. Usually runs rough after it has been driven and restarted.


A VERY Recent Tune Up MUST Be Insured to Properly Diagnose this Discription, If the Vehicle Has Not Had A Recent Tune up That CAN be the Cause of Your Symptoms, If it HAS been Tuned up, then With these Symptome the Check Engine Light Should Illuminate, and If the Light is On It Must Be Checked For Codes and Fallowed up From there. If No CEL Try Changinging Fuel Filter, As This Will Cause Poor Performance Without Turning ON the CEL.

2000 jeep grand cherokee 4.0 liter engine timing belt replacement


If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.

I have a Jeep Cherokee Laredo 2001. The check engine light is on and I have been told that the computer is diagnosing the problem as a misfire in the cylinder. I went out to try and change the spark plugs...


assuming this is a 4.0 liter engine it doesnt use plug wires any longer....it uses a coil pack. this runs down the passenger side of the engine and the plugs are under it. 4 13mm headed bolts hold the coil pack to the engine assembly
