So i just finished installing a bbk 70mm tb and im having hesitation issue, after warming up driving it, it seems to hesitate /loose power at 15/20% throttle. It kinda does out and i have to press the throttle a little more for it to drive okay.. Idle is pretty high 2500rpm. I have checked all my vacooms and everything seems to be fine .. Intake mani is matched to the tb btw ... Im not running any ems at the time just stock ecu, i checked the tps and its calibrated .. Any other ideas ?
