Acceleration hesitation
I have a very specific hesitation that hits @ 2400 RPM on the dot. Not 2200, not 2300. At partial throttle its very obvious, feels like a car from the late 80s when the ac compressor kicked on and the drain you felt. Its not AS abrupt WOT but I can still feel it. It is NO WHERE near as abrupt when the car warms up but again, can still feel it.
I've replaced the MAF and 02 sensors. I've smoked tested the intake, and hooked up a fuel pressure gauge. There is 0 fuel pressure drop at partial throttle and drops 3-4 PSI at WOT which seems to be normal range.
Anything else I should be looking at?
