i know you said you checked the maf but sometimes the plug looks like it is on when it is actually loose. i tore apart my engine bay looking for a problem when i just needed to plug in the maf lol

yea we check that haha. we even made sure it was getting the same signal at the ecu and at the maf. and everything looked good. i think it might be a fuel pressure problem. because i would spray a little carb and choke cleaner in by the pvc and it would revv normal about one or two times. so mabye not enough fuel? how could i fix that
