The thing is when I start reving at about 5000 my car trys to shut off but I think it is an O2 and how many are there anyways?
And it also starts doing the same thing as I am slowing down almost as if it doent know how much gas to send to the engine.
The mechanic said one O2 sensor wasn't working properly but I dint want anymore testing because it was costly
