I noticed yesterday after starting the car up and pulling out of garage and placing back in park, the rpms would surge from 1 to 2, back down, back up, until i pressed the pedal down hard to increase the rpms. Its as if im on a starting line ready to race someone. I was thinking throttle body or, air intake, dirty air filter??

Any ideas?

 

Its your IAC valve. Its dirty and needs to be cleaned or replaced
