Have you tried clearing all codes? You may have an intermittent issue (electrical) that may be as simple as a loose gas cap.

... I have cleared the code twice I do get from time to time to loose gas cap indication .. by clearing the code I mean removing the ground cable from the battery for 2 hours or more .. two places AutoZone and Advanced Auto when they've seen this before it was either a short or the computer is going bad .. comes up with a blank screen 0 nothing on the analyzer at all .. just trying to get some feedback before I spend 400 bucks on a new computer ... Thank You ...
