Acceleration hesitation 2001
Occasionally, when accelerating hard, there’s a slight hesitation at 3500rpm and a noticeable drop in power. Other times the engine will rev to red line with plenty of power. Where should I look for problem? Only have 109k and plan to keep the vehicle. Thanks for any guidance I can get!

Could be MAF. Log your LTFT to see how much correction there is during closed loop. 3600 RPM is where the ECU transitions to open loop and depends solely on MAF for fuel calcs.
Or could be the knock sensor/wiring. It doesn't trigger a CEL, but will throw a ghost code.
