holy shit wait....get that o2 plugged in. its a huge part in running your car correctly. stop driving the damn thing until you get it in.

The top O2 sensor is a wide-band and is key to your engine running. Do not drive it without it correctly installed.

didnt ken already tell you not to drive the car without the o2??? your wondering why its not running right without the top o2, its what the ecu uses to tune the car. stop worrying about plugs and fix your o2 sensor. your problem will be solved.

and yes they will make a difference compared to stock once you put your o2 sensor back in.
