    Default Random misfire cylinder 1,3,4. Help!

    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?

    no, everything is original. Its a obd2 car and motor, vin plate is still on motor and tranny. I'm going to try to fix the plugs, cap, button.

    But as far as the o2 bung not being there on the header, do I just need to get a new header so I can put a o2 sensor in?

    Your oem cat should have the o2 bung there. If your using aftermarket cat I would take it to a shop and let them weld you 02 bungs.

    Misfiring part, check your spark plugs.

    You can take your header to most shops, and they can put a bung in for you, one should be in header, one should be after the cat (or in it)
