Hello again, Thanks for the help Mr Teitelbaum, you were right! but not first:). Nick Pitello helped me out earlier today and we found the problem. The 3 screws on the intake were almost completely backed out all the way. I turned them all in and now the car runs much better. It still needs a new 02 sensor, tomorrows project is getting the old one out. what should I put on the threads when installing the new one? Thank You all, I really appreciate it. David #2496
