Ok, tell me this... What engine? 4 or 6? Also, how many miles. Mine does the same thing. I put 20-50 oil in it and it does ALOT better. stays at "the middle" while rpms are above 1500, and dips to 0 and then rises to 1/4 at idle.armybuck041 said:Thanks for the great advice...
i'm gonna give the mech gauge test a whirl. All signs point to the pump Thats the price of having fun I guess.
