Replaced coil pack with no change. Went back and checked the maf sensor for the heck of it and it's shot. This would affect the overall power, correct? I'm wondering if it was intermittently going whacky while driving. Car no longer lopes on start up, but still a big hesitation between 2,500-3,000 rpm. Like I can roll deeper and deeper into the throttle and the rpms won't pick up until it downshifts.
