If you would just replie back to this question you would get a lot more result's then answering the same question again. Also does your engine burn oil?If so how much oil in 3,000 mile's?Also answer the other question's I asked. How old is you cat?When was the last time you changed your spark plug's and wire's. Also any code's?
