Well ive tried some of this stuff still nothing. Getting ready to swap maf sensor from friends truck to see if it helps. a friend was looking some stuff up and some other ppl said fuel pressure regulator? What bout fuel filter? It seems it may have a little loss of power. I dont know. Im averaging bout 9 to 10 miles a gallon.
