So after installing my aftermarket exhaust (which sounds great by the way) I pulled the O2 sensor off because it was dangeling... talk about a mistake! I cut the wires and now the car won't idle long enough to run.:icon_cry: The car is stranded at the MDOT. Will an O2 sensor do this? What is the wiring behind these things because I traced and cut the wires atop the motor? Thanks!
