I recently went with Blue Chip, it turned out the cause of the previous failure was water. I didn't know that until I damaged the new VP. After a call to Blue Chip technical support and their help diagnosing the problem I returned the new Blue Chip VP for cleaning.

Doug at Blue Chip went far and beyond what I expected in diagnosing and getting my new unit serviced. They also made great recommendations for tank cleaning and a better fuel system.

Hands down the way to go.

 

. . My truck did the same thing after I did some work on the injector pump. . After spending a lot of money on un-necessary parts a friend asked if I had reprogramed my TPS. . I'd never heard of that. . Turn the key to on but do not start the engine. . Slowly push the throttle pedal all the way down and then back up. . Took care of the problem. . . .
