Ok, I've searched on H-T and there were numerous of different answers. Main answers were to change the rotor button and plugs which I just picked up today. The car is a '96 gsr, its runs fine, idles fine, no problems so why am I throwing this code? code 71-74.
Also I'm throwing a code for both o2 sensors. Here's the catch, on the header (dc sport) there is no o2 bung, so how would I go about fixing this?
