2007 Jeep GC Engine Issue

Asked by Sep 21, 2016 at 08:48 PM about the 2007 Jeep Grand Cherokee Limited

Question type: Maintenance & Repair

I need your help!  I have a 2007 Jeep Grand Cherokee Limited 4.7L V8.  The problem I am having is two-fold, but I'm not sure if they are related.

Problem 1 (the biggest problem): Occasionally the engine will drop RPMs while idling, and it will "jerk" during acceleration.  It feels like it a misfire. Usually it only does this up to about 25MPH, but it has done it a couple of times while going about 70MPH on the freeway.  I have had the spark plugs replaced, faulty coils replaced, transmission fluid flushed and nothing has solved the problem. All of the techs have not been able to exactly pin-point the problem.

Problem 2: The tire pressure warning light and notice stating "SERVICE TIRE PRESS. SYSTEM" will flash for about 20 seconds, then go away.  All the tires are at the correct pressure and do not have leaks.

One tech mentioned that the problem may be a faulty computer which is causing the fuel injector to work improperly, but as I stated earlier they have not been able to exactly pinpoint it as the culprit.

Has anyone had this same problem(s)? Do you have any suggestions for solutions I can look for?

On my old Jeep Grand Cherokee the TPMS light was doing the same thing, I found just 1 of the sensors would intermittently fail if the vehicle exceeded 68MPH, replaced just that one sensor and the problem went away. Just before the trany went south at 80K during crusing it would feel like it would jump a gear, it would only do it once unless you slowed down to 25 and then back to freeway speeds, then it would do it again, 1000 miles later the tranny went. Fluid was still bright red and did not smell burnt, the tranny guy said that he found a couple of snap ring pieces in the pan when he pulled apart.
