O-2 sensors on cat...two of them?

[Mollow]

i want to get a HFC for my gd3 and yeah i looked at the stock one and there are 2 plugs? i know one of them is a sensor but not entirely sure what the other one is? i was thinking of getting the weapon r headers on ebay but yeah i dont want that engine light on in my car.......how do i get rid of that too?

[ouch]

hmm, dont know what you're on about here, but i still think you should just take off your axle back. kthxbai :)

Yep, some cars have 2 oxygen sensors

what year is your car? i think onlt the 05+ model gets the Engine light problem.

because xForce say that only the 05+ models get the light error on their CAT system

i dont see why the weapon r ones would be any different.
