Anyway, you need to put a scanner on it and see what's happening when it does that before you waste any more money on needless parts.
after reading update , sure sounds like cat clogged, or muffler. easy test for that is vacuum gauge. but again, mr TBI says it best when he says use a scanner, it too will show vacuum issues and other parameters.
yes, and always some confusion as to which it is and its location. one feeds ecm, one feeds temp gauge/light. the autozone guy will almost always bring you the wrong one, and you tell him its the other one. lol
