I just got my Berk HFC's put on this past weekend and today i finally got to open it up on the freeway on the way to work this morning. i noticed if I am cruising in 6th gear and the engine is revving between 2800 to 3000 and I step on it, the engine seriously hesitates until it gets over that 3000 mark and all of a sudden it accelerates. I did not disconnect my negative battery cable after, would that have anything to do with it learning?

 

Wow that's not good!! I just got my FI HFC's put on my car. I has that bad hesitation in the same RPM area in any gear! But mine was caused by a by a bad 02 sensor in the header! Which the dealer damaged during the install and replaced it free under warranty! After they changed that all my hesitation is gone so far I hope! Do u have any CEL showing? Since this cars ECU is so sensitive! Make sure there is no leaks in your exhaust at all! And if u have a CEL on, make sure u get the codes read to see what sensor is causing it. Or try reset ECU to see if that might help! Good luck bro!

 

No lights on in my dash

 

Whats the best way to reset the ECU?

 

I just disconnect the battery for like an hour. Or do the pedal reset. Not sure how that one works. Or do a search here for how to do it

ANMVQ had a 5AT while the OP has a 6MT. Similar but different.
