Sup guys I have a 08 g35x. A couple of days ago I went to back my car out of the driveway, and when I switched into reverse from park, my car died on me. I shifted into park, and turned the car off and tried again with the same result. On the third try, I went right into neutral, than park, and It worked. It has been working ever since, and has not died on me yet in reverse.

I asked around and most people are suggesting its a throttle body/idle air control valve issue. I cleaned the throttle body in the summer, but I don't remember cleaning an IAC. Does our cars have an IAC? If it does, can someone point it out for me?
