    '16 Scat Pack MMX Chopstix cam + MMX tune, seldom won't start, dies in gear

    Just a couple of minor issues:

    1) Sometimes when I have been driving around and i stop at a gas station, it will crank, but not start on the first try or unless I give it some gas it will.

    2) If I put the car in gear, drive or reverse, too quick, it will struggle and die. It's not all of the time this happens, just when its hot outside and I have been driving around. Also, if you go from Park to Neutral and let it idle for a minute then put it in gear, it won't die.



    Otherwise, the car runs great! Any ideas what can be causing this? I'm going to attach my tune to help troubleshoot this issue.

    Air intake issue: A problem with the air intake system, like a dirty or malfunctioning mass airflow sensor (MAF), could lead to difficulties starting. A malfunctioning MAF can disrupt the air-fuel mixture, making it harder for the engine to start.
