Is it strange that my injector duty cycle is between 9-14% both at idle and cruising at 65mph?
That seems like way too much fuel at idle, which is odd because I leaned it way out on the VPC.

Also the fuel trims are all stuck at 100% because the O2 sensor is dead. I'm considering either a wideband to tune this thing or just running gasoline for the winter since I'm guessing my chances of the car starting in -5 degree weather is about zero.
