#4531 of 4622 Rattle in front end by Mossstone Aug 31, 2009 (8:44 pm)
I have a 2000 Grand Cherokee 4.7L with Quadratrac. I have noticed a rattle coming from both front wheel wells when driving on rough pavement. Any ideas what may be causing this?

I have a 2002 JGC that i bought this past summer. The check engine light came on and I took it to adavance auto parts and the guy told me it was just the gas cap that needed to be replaced. He also said that it would take a couple of days of the light to go off. Is this true?   Also, my jgc has started burning gas like crazy. I drove about 15 miles today and it said I used about 45 miles worth of gas? How can I improve the gas mileage? Replies to this message: firefighterjoe (Sep 15, 2009 2:49 pm)

I am trying to fix my sons 2000 Jeep Grand Cherokee. Its has an inline 6 cylinder. When in park and giving gas it runs and sounds fine for about 3 seconds then starts to hesitate etc. In gear it runs rough and can only get it to about 40 mph.   Just had the plugs replaced   Thanks in advance!

Replying to: russ543 (Sep 11, 2009 12:31 pm) Possibly the TPS or a clogged fuel line/filter? Replies to this message: russ543 (Sep 11, 2009 1:08 pm) tidester (Sep 11, 2009 2:20 pm)

#4539 of 4622 change the fuel filter by wpatters Sep 11, 2009 (2:51 pm)
You would be amazed at how that affects the engine. If the fuel pressure is down the computer goes nuts. Simple to fix and even if it is not the problem it probable needs to be done.
