a slight Problem slowly getting worse
i have a dead spot where the car isnt making power its about 3.6 and 4.1k rpm, im guessing its when the injectors switch over to the secondaries, Not sure where to start looking, any ideas

The 3800 RPM hesitation is common on older FCs, and can be caused by:
#1 bad engine grounds
#2 Dirty injectors
#3 stuck aux ports (on non turbos)
#4 bad ECU grounds
#5 bad BAC transistor in the ECU (usually related to Joe Idiot trying to check the BAC with a testlight).
#6 misadjusted or bad TPS (on S5 cars).
