Having problems with your 2000 Jeep Grand Cherokee ?

Help I have a 2000 Jeep Grand Cherokee Laredo 4x4. Recently, it started surging on me. While I am driving, the oil pressure gauge will go high then return to normal. While it is doing this, my RPM's go low and high. Any suggestions? I have had the spark plugs changed but, the guy told me it doesnt have spark plug wires. I have added injector cleaner, changed the air filter also. Maybe needs a fuel filter? Any suggestions?

Hey, I just had the same rpm surging problem... really bad all of a sudden over the last couple days. The check engine light came on today and it's idle changed from big time shaking to barely a pulse. Drove okay on the highway on our way to my favorite auto repair. A diagnostic showed that the third spark was dead and upon the advice of a senior mechanic  - spark plugs were changed along with the coil. I dunno if that was smart on my part I could have tried just the plugs first. But I figured I have never changed any of these before and it is getting older. So with a new coil, spark plugs and minus $375 from my world - ... but it's running pretty well now. 
I had the same problem and I found out that the battery was bad. since everything runs off the computer there wasnt enough juice to run both the car and the computer the jeep ran good after putting a new battery in it. so try this first before you spend a lot of money on a shop fix because they wont think about the battery being bad. they will want to replace everything but. hope this helps

Failed e-test My 1992 colt failed it's e-test. The NOx was way too high. The car runs good, except it chugs a little at the 80 km mark. I've changed the distributor/rotor cap, spark plugs, fuel and air filters and spark plug wires. i think i'll change the O2 sensor. Any suggestions.


O2 sensor helped me but not enough to pass. Loosen your distributor bolts, one on each side, turn your distributor counter clock wise about 1/4 inch and tighten bolts. This will raise your CO but should reduce the NOX. When the vehicle is passed, und ... 1992 Dodge Colt

Normal idle speed with a warmed up engine is 700 RPM on the 1992 Honda Accords. The Fast Idle Valve may not be kicking out, or a mechanic may have raised the RPM to hide some other condition. Either way you should have this fixed by an honest Honda m ... 1992 Honda Accord

My 2004 Ford Expedition 4.6l has a rough idle and occasionally backfires. My check engine came on and I had it diagnosed and it said it was the O2 sensors. I changed all 4 sensors and the mass air. I searched online and was suggested that it was the PCV valve which would send a false O2 sensor code, but just found out on fixya that the expedition doesn't have a pcv valve. Any suggestions on what it could be? I have changed the air filter, fuel filter, spark plugs, O2 sensors and mass air.


Well i'm sorry that you got the miss information here on fixya. because all internal combustion engines need a pcv valve to operate properly.now the information you got first is correct and pcv valve can set false codes like o2's and lean ... 2004 Ford Expedition

2004 Nissan Altima 2.5S - Did a tune up, replaced spark plugs, checked gaps, started running rough as if there was a misfire. Every now and then the car jerks and has trouble accelerating.

My 98 Chevy Metro will only start after it has sat for two hours or more. It starts right up in the morning, but if I make a quick stop, it won't start back up.
