Asked by bsthornton Jan 28, 2016 at 06:46 PM about the 1993 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I have a 4.0 engine, automatic, low mileage 130,000. All of a sudden
it started to run rough at park or idle. I check the vacume lines OK
and battery is good. All fluid levels OK. It hasn't been
overheating.tranny was flushed last year and new radiator. No check
lites except abs light is on. Just had oil changed 1500 miles. So does
the high oil pressure and rough idle/dying have in common PCV?

Just the idle. PCV may needing replacing, check the vacuum hose for cracks, check all vacuum hoses for cracks and replace as necessary. Oil pressure sounds good. Also it just may need a tune-up. The ABS code would need to be read by a scanner to see what it is. It can only be reset when the problem is fixed, and the code cleared by a scanner.

I have a 2004 Jeep Grand Cherokee Laredo V8. Was sitting at an intersection and the oil pressure just went to zero and my "check gages" light when on. I checked the oil the day before and oil level was fine. Anyways, in the parking lot i happened to have a quart of oil in my jeep that i dumped in. Feeling risky i started it up and the guage stayed good for a bit and then dropped back down. Feeling even more risky and desperate to get home i decided to drive it 2 miles to get back home. As i drove the gauge almost routinely would dip to zero and the "check gages" light would come on. Then it would go back up to normal for a few seconds and go back down to zero for a few seconds. It continued to do this the entire two miles. You guys have any ideas? Its got about 169,000 miles on it, and i just put a brand new oil pan on it. 5 Answers
