I did the 00VI swap, it was working fine until it started getting hotter outside. When It's hot and I go to start my car it has trouble starting like it not getting enough air through the throttle body so I'm throwing a 13-02 code MAF. Sometimes doesn't start but the next time try like a second after it will after acting like its going to die.Anybody know what it could be?

 

also have a 03-04 code for my knock sensor.
