Cant Figure This Out!
Cant Figure This Out! Recently i have been getting the P0171 left bank lean code. At first it wasnt that bad but now the car is sputtering real bad. I changed the plugs and the MAF and even the O2 sensor but its still sputtering. I ran a scan on the O2 sensors and it seems when i go past 40% throttle, the O2's just read 01-50 instead of fluctuating.
I have recently had someone install the walbro fuel pump and wiring harness and its also getting the P0440 code for the evap system.
My main concern is the sputtering as its affecting the car's performance greatly. Any suggestions?
