  1. I'm stumped. I have an 03 mach 1 with 28k miles. it runs good most of the time but when coming to a stop it sometime drops down to 500 rpm or lower and then jumps back up but it has never actually died. hooked up my diablo and it threw a few codes. misfire at startup, misfire on cylinder 3, and cylinder 5. and it said bank 1 was lean. Again NEVER does it when driving just when coming to a stop. What could be causing this?
  2. did the check engine light come on and flash? did you try swaping coils to change the cylinder misfire?
  3. Post this question on You may have to sign up but if you have a Mach, that's what this site is all about. Could be dirty MAF screen, fuel filter...a number of things that are beyond my abilities.
