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?

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!

Possibly the TPS or a clogged fuel line/filter?

TPS = Throttle Position Sensor

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.
