The ONLY issue i have is when i floor the jeep from a first gear stomp, it hits rev limiter for a solid second or two before it shifts to the next gear. I have watched quite a few youtube videos with 0-60 runs and none of them shift slow. I have 5,7 Hemi 2006, 30 miles way to work daily and i have average consumption 8-9ltrs/100km (about 31 - 35mpg) Jeep Grand Cherokee 2006, 5,7 HEMI, US Limited 4xGuard F&R skid plates, OME HD coils, CB Albrecht AE 6690, Hella FF200, Yokohama Geolandar A/T-S 245/75R17, 30mm spacers, Bilstein 5100 F&R, DynoMax 3" muffler w/ Magnaflow 3" - no 2017 GC, 5.7 Hemi Not starting. Issues started a few days ago, When pressing the start button, it will take about 5 seconds and starts the Jeep. However after few days, (It was parked as I didn't drive it) I tried to start the Jeep, and everything turns on, but no crack. I checked the battery voltage using the cig lighter in the armrest and it Wash the engine, radiator, underside completely, then add the dye and drive a bit. Check in a darkened garage or with a blanket over the hood to make it a bit easier to see even small amounts of dye. If all else fails, pressure test it--with dye. If still nothing, compression test all cylinders for a gasket leak. A. For the 2005 Jeep Grand Cherokee pcm problems, the car will show different signs that one should take seriously. The most notable one is the squeaking noise heard whenever one is making turns. This could be accompanied by a feeling of loose steering. Whenever you identify such a problem, ensure you get a proper diagnosis from a mechanic you trust. Watch on. The problem is the roller lifters used by FCA between 2009 and 2015, the needle bearing fail in the roller and then gouges the cam lobe. Previous explanation was bad oiling during idle. Read the comments below the video on youtube, the recommended aftermarket replacements most have oiling holes or improvements to get oil to the needle My 2007 Jeep Grand Cherokee 5.7 hemi is doing the same things. It will ding, check engine light will flash and and it will jerk and gear down, it has made my back tires screech it does it so hard, then it will go back to normal gear. It's done this multiple times before and it's done it to my mechanic as well. Help! 2007 Gr Cherokee Stalling. My 2007 Gr Cherokee Limited (5.7 Hemi 145k miles) has been stalling. It does it when driving and temp, weather, speed, etc have no effect on when it stalls. It has stalled at idle, too. Took it to the dealer and have replaced the starter, PCM, spark plugs, had a throttle service done and it is still stalling out. 6Vapl.
