Replying to: sarwarrior (Nov 08, 2006 4:09 pm) did you check for fuel pressure ? you might have a vacuum leak also. try your plug gap .035 is whats recommended i think. refer to your label in front of the the radiator or call your local parts supplier for info.

#538 of 589 JEEP GRAND CHEROKEE 5.2 4x4 PCV IDLE PROBLEMS!!! by sirpilla Jul 14, 2009 (12:16 pm)
I have a 1994 Jeep Grand Cherokee Lerado 4x4 all wheel drive with a 5.2 Liter(318) engine. Computer only throws an end code when trying to read with key turned 3 times and Auto Zone and Advanced Auto both said it's too old to read the codes with their meter. Last year I replaced the Cap and rotor along with the spark plugs and wire and now Within 2 weeks I have Replaced the Spark Plugs, Trottle Position Sensor, Air Idle Control Sensor, fuel filter, fuel pump checks out fine, PCV and hose that connects it to the engine were replaced twice in a week, cleaned all 8 fuel injectors and replaced all 16 of their O-Rings. fuel rail pressure is and was before cleaning injectors, exactly in spec 31 psi off and 39 psi when started. being despirate to try anything we added SeaFoam to the Valve cover and gas tank as a last resort and yet STILL after all of this it has a rough shaking my Jeep idle! When the PCV hose is hooked up, it starts and stalls, when you disconnect the PCV from the hose it stays running with the sluggish rough idle but it is the only way to keep it running! The minute you plug in the PCV the engine dies and doesn't want to restart until it's unplugged again! HELP ME PLEASE, I LOVE MY JEEP!!!
#539 of 589 09 stalling issue by raelinda Jul 22, 2009 (9:26 am)
2009 grand Cherokee (14K miles) stalls when slowing down for off ramps or lights dealer has replaced computer and ignition - did 3rd attempt for lemon law but they can not make it die so nothing wrong with it - we can not make it happen but it has died since computer fixed. now waiting for lemon cases to move forward due to sale of Chrysler.   Any other ideas of what we can check to prove there is an issue?
#540 of 589 Re: Electrical Starting Issue JGC 2004 -ODD!!! [bandit71] by spriest Jul 28, 2009 (2:31 am)
Replying to: bandit71 (Nov 03, 2008 9:24 am) Bandit71,   I had the EXACT same problem yesterday. My issue began after the vehicle was running. I heard a loud pop from the radio speakers and observed the voltage gauge floating while driving. After I got home and turned the Jeep off, it would not crank. No interior or brake lights, nothing at all that indicated I even had a battery connected. All of my gauges were pulsing and flipping over wildly with or without the key in the ignition and I could hear a faint clicking noise timed perfectly with the pulsing of the gauges. I let it sit for about an hour and it finally looked normal on the dash and sure enough - it turned over fine and all my gauges are back to normal. Even the pre-sets on the radio are still there. The only noticeable difference is that my clock on the radio is wrong. Did you ever find out the problem? Has anyone else encountered this problem and if so - what's my next step in troubleshooting this issue?   Same vehicle - 2004 Jeep Grand Cherokee Limited (83k)   I need help!!!

Replying to: diamond25 (Aug 03, 2009 4:10 am) Not a clue. still working the issue. b/c it's hard to duplicate the problem at will, it's hard to narrow down.
