On the '02, you can pull codes from the odometer window using the key. Starting in the off position, turn the key on-off-on-off-on, leaving it in the on position on the third cycle. The odometer window will flash any codes present. If there are no codes, it will just show "P done".

Post the codes here and we'll interpret them.

Check your fuel pressure. If your lift pump is going bad, you may see decreased mileage. Easier than throwing parts at it that may not help.

 

ok and i do that how?
