i can drive the teg and out of nowhere it will just start running like shit. i check my wideband and something (i think its the ecu) is cutting my fuel but if i slam the pedal im guessing it overrides the ecu and dumps fuel into the motor and it pulls again but not instantly like it should. motor is brand new with only 400 miles on it. current ecu is a pr4 that is chipped and reflashed to run turboedit. i have plenty of spark cause i have a new 6AL. my fuel pressure gauge is reading about 42ish psi. the car messing up is very inconsistant. as i was breaking in the motor on both occasions i hit 100mph i stayed in gear and let the car slow down on its own (heard doing this letting it build back pressure helps set the rings) i got a check engine light and my fuel became really lean. now it does it whenever it feels like it. any suggestions? if someone can help me fix this really quick ill hand out a small reward
