Check Engine light, low power on 98 RAM 1500

I have a 1998 RAM 1500 Quad cab, with the 5.9L magnum engine, and auto tranny. The problem is, the check engine light won't go off. I've even taken it to the local mechanic, and they couldn't find anything wrong with it. (I live in a small town w/ no Dodge dealer.) Does anyone have any idea what it could be? A sensor of some sort maybe?
Also, the truck seems to be dogging it up hills, and I think it should have more power from this engine! Also, I only get 7.9 MPG. Could this be related to the check engine light in any way?
Thank you,
Jed Smith

howdy / you need to get to a shop that can read the CODES that are in your truck / that or get the book that tells you how to read the CODES yourself / it could be anything making your truck run like that / from a bad O2 sensor to a clogged CAT verter / you NEED to get the CODES to fix it / you can spend a lot of money throwing parts at it to try and fix it and not hit the right one / good luck and MOPAR TO YA //////////////////////// WED

Check the cat.
My son's clogged and cost him a head on a 5.2. No one could figger it out. Anouther symptom on his was that he could not maintain speed in 5th gear. We found it by accident while we where upgrading exhaust.

If the engine light is activated there will be a code stored on the OBD (on board diagnostic) module that will help pinpoint what the cause is. As mentioned, you need to get to either a dealership or a reputable garage that has diagnostic equipment to read the codes.
