Have a 90 quad 4 Gr. Am with a problem we have not been able to solve. On start up it idles and runs fine. After about twenty minutes it still runs smooth, but when coming to a start the idle becomes rough and will stall out. After about ten minutes or so it will start and run fine for about another ten minutes or so. We have changed the computer, tuned the motor, and changed the cat. No noticable improvement. Cleaned the injectors, and other things which I do not remember at the moment. After it stalls out the motor will start and idle fine in Park or Neutral, but upon placing it in gear it "clunks" and the engine stops. I would be grateful for any ideas.
