I think the O2 sensor is on the exhaust pipe ahead of the CAT. Get an O2n sensor socket and remove it like a spark plug.
true duals means two separate pipes all the way from the exhaust manifold to the tail-pipe.I don't know anything about dual exhaust. What are true duals? I guess they are. I'm taking that nonsense off in two weeks. I don't like that noise. The guy who works on my car said it had an expensive muffler on it because he recognized it. The cat should be fine because I think you have to replace that in order to put the dual exhaust on. Hell I don't know. I just know I don't like it. This car is in pretty good shape but was about to be ruined. LOL.
Probably just get to it and replace the actuator.Anyone know how I fix the blend-air door?
