as you guys know ive tuned my 300c many times trying to get it better and better. im at the point where im trying to get my startup to be clean and no misfires. ive gotten it to 0 misfires on startup and none while driving but hard to start cold! when i get it to start without touching the pedal, i have misfires on startups and while driving. im still playing with it but im noticing my throttle voltage at zero till about 1/4 push and i get voltage and the car responds. im gueesing check the voltafe with my snapon modis scanner to see if its the app sensor or something else.
