Hey Racerxb20Z, like I asked, did u try to repair or modify something previously prior to the problem? If this just happened without u touching anything then more than likely one of your injector is failing; either stuck open or close. Code 16 is a fuel injector fault. If u did messed with it prior, then u might of switched the 2 injectors connector. I know exactly what your problem is. Let me know if u need instructions on how to check your injectors. Don't take it to the dealer when u can fix right here. Good luck!
