If your EEC has been reflashed, there will be a sticker on the radiator support indicating the new code...unless the dealer forgot like they did on mine when I got the "stall" flash.
Well i got this car not to long ago i got this car from MICHIGAN i live in FLORIDA i just checked the door jam and it says YDH1 does that mean i got to get it reflashed, i have not had a stall since purchase and no sticker on radiator. Although i did dynoed low numbers if that means anything
