old problem
i know i no longer own the car and shouldnt worry bout it, but it still bothers me.
you can see my list of mods at the bottem basically bolt ons no tune. i also added the delteq opti system.
now i had a really bad miss under close loop between 5-5700 rpms.
random misfire codes and that was it. i had a new opti then the delteq system. the new opti was a msd billet.
all new plugs and wires, nothing jumped out and said HEY on the scan tool. the car had 110k miles on it. i had walbro 255 with aero reg.
any ideas?
