I just got a 1000 lph fuel pump installed and now the car sputters at low rpm and bit into mid range. Could It be the 02 sensor because right now i have my turbo kit installed with a stock p3 ecu out of a 00 civic si. and it didnt do it before i got the pump and lines installed, but, now the one of the stock 02 sensors are in. Could the sensor be messing with the fuel mixture?

 

damn, thats a big fuel pump volume, what is your set-up??

you might need to lower your fuel pressure to compensate for the hi volume fuel pump.

seems like your running real rich
