When I’m driving the car around and come to a stop, my idle drops from 900 to 200 and feels like it’s about to die. It goes back to normal but as soon as I come to a light it drops again. Once I park though, I let idle for awhile and idles normally. Only happens when I start moving and stopping at lights. Anyone know what’s wrong? It’s not throwing any codes as well.

 

Vacuum leak, dirty throttle body, open air filter without a heat shield being effected by the radiator/AC fans are the things that come to mind for that issue. Could be other things too, but that's where I'd start.
