Well, the glug glug noise is still present. I took the W pipe off and checked out the throttle plates & deceleration valves. There was some light black soot-like gunk on them, but not too bad. It wiped right off. The valves open freely if I depress the springs. I also replaced the oxygen sensor just for kicks. There was no change in the sound. Everything is still the same. I did notice a tiny bit of oil in there, around the throttle plates & in the W pipe. Not very much, though - a few drops at most. Is that normal? Anyway, if anybody has any other suggestions I am open to them! -Ryan --- In dmcnews@xxxxxxxxxxxxxxx, "ryanpwright" <yahoo1@xxxx> wrote: > > > My car lets out a "glug glug glug" when I decelerate.
