yea......... any where from 79-82mph 3900-4100rpm my car has a hesitation prob,
when i give it more throttle it hesitates then like a switch the power comes back on. i was just wondering if this because the waistegate is open at that certain rpm or not, im hoping thats why. if anybody else has input on this let me know thanks:confused:

make sure your recirculation valve is functioning correctly, i pinched my recirculation hose when i was regrounding my maff and didnt notice when i did it. i dont get on my car every day but when i did gety on it after the reground i noticed the SAME problem. Choking up at WOT at or around 5000 then picking back up again but not as hard
