Idle Surge

Idles at around 1500 then drops to 1000rpm and keeps doing that. But when i turn on all the lights and air conditioning it goes back down to 1000rpm and doesnt surge. Could this be a bad Idle speed control?

I'd also vote for the ISC. I've had the same problem before. I replaced it and blocked off the FIAV and was good to go
