That tube that trixzta is talking about is not on your car. That started in 1997. Pull the front 02 sensor and see if that helps. That will reduce the backpressure. You could also have a shop check the backpressure. |
I was wondering where this 02 sensor is, is it on the cat or somewhere else?? Also when i start it up and the engine is cold the rpms struggle to rise when i hit the gas and it sounds like the cat is choking, it sounds choppy, i will post a vid later of the noise
