can you adjust the idle? mine is at around 500, how do you raise it to 750? reason being is that i bought a pro-flow maf and i have it running at .8 volts and the idle is still somewhat erratic and stalls sometimes...pro-flow says to raise the idle speed at the throttle plate, but i don't know how to do it...i really don't want to put my old maf back on and lose like $450.00 in the maf and optimizer...thanks in advance (i did do a search)
