2002 Jeep Liberty Sport 3.7L V6 - Won't stay running; grinding and knocking from engine

2002 Jeep Liberty Sport 3.7L V6 - A couple of days ago the jeep just died. When it turns over you have to push on the gas to get it going. If the RPMs drop below 3,000, it dies. Now, trying to start it that same way...the engine started knocking and now makes a bad grinding sound....what the fish? Any ideas? The oil was changed 2 months ago and we just filled the gas tank at Albertsons...then about two hours later, it pooped out.

SOURCE: jeep chocks, stalls, rpms shoot up n down n dies

Check fuel pump for pressure and output. If it's not that, don't start guessing... have a scanner put on it and get some codes. While some codes can be ambiguous, it will serve to start you in the right direction!

check the fuel pump fuse/relay, could be just bad enough to cause an intermittent start/no start. and check fuel pressure,spark and the crank position sensor.

SOURCE: 2003 Jeep Liberty. Changed oil, running very rough and dies.

Buy some Marvel Mystery oil from Auto Zone and add it to you engine oil. Keep an eye on your engine oil level everyday with the Marvel in there and change the engine oil every 3000 miles. Hope the Marvel will clean out the lifters for you and the rest of the sludge in the engine. Do Not Use Engine Flush!!!! There know to eat the seals and kill engine sensors.
The EGR could also be stuck with carbon build up and may need to be cleaned or replaced. Try doing this, turn your radio off and disconnect the battery for a min, turn the ignition key to the run position and re connect the battery then start the liberty. That should reset the air idle control valve
Let it idle down and then go for a test drive after it warms up. Good luck and keep me posted, while your at Auto Zone have them scan your liberty for any DTC codes. Be glad to help.

2005 Jeep Liberty Sport. While the car is running, I notice the dashboard and headlights dim every minute or so for a few seconds. Also, the car doesn't start as smoothly as it normally does. This started...


I have an 2002 Liberty had the same/similiar problems, have the dealer check the wire harness that runs underneath the driver's seat, my wires had gotten wet from somehow and it caused the wires to corrode, they had to replace sections of the wire harness to fix the problem.
