I did one of those OBDII test the other day for because my CEL kept turning on, and it said that I the 02 sensor was lean on sensor #2 in
bank 1...which is the rear sensor on passenger side (i think). So i changed the sensor and reset the computer (unplugged the battery) and the CEL came on again. I am thinking that it is because I have duals, but NO H-PIPE..just straight headers to mufflers with cats. Does the H-pipe really balance the flow that much to trigger my CEL? I need to get smogged soon and with the CEL on, I will not pass. Thanks for the help....a1
