Rebuilt motor big cam big heads big intake big tb the problem is that I adjust my throttle body it's 90 mm fast it had a hole in the blade and guy welded it shut so we drilled it out to a 1/8 . I fire car up it don't wanna start unless I open up blade enough then it runs high I adjust screw. An it's tuned right then after a while it's idleing at 1000 it jumps to 1500 then down to 600 then back to 1000 an does that over an over .Ok now I put my intake on an maf won't start unless I open blade more get it running then adjust it runs fine then I rev it an it cracks Loud threw exhaust only does it with the maf on what's goin on here it's all tuned with ecu
