Can a bad IAC cause a rough idle?

Post by BosnianLanos »

Red Lanos is experiencing a rough idle. Revs drop fairly low, but it doesn't stall, made worse by hot weather/hot engine. Above idle, the car is fine.

Can this be caused by a dirty or faulty IAC? It hasn't been cleaned...ever. Which I know is terrible and unlike me.
