Low idle

[ViperCLKGTR]

Truck had idled low maybe two times in the last month, just about 500 RPM a quick blip of the throttle and she would go back to 750 RPM. I figured next oil change, I planned on changing plugs, cleaning the TB, and a few other little tune ups I'll clean the IAC then. Well today from the first stop sign I pulled up to till I turned her off to walk into work she idled low and at some times low, low, low every time I came to a stop. Average idle RPM was 400-450 RPM but twice it even dropped a few times below 250 RPM.

Good thing I'm changing the oil this weekend haha. I figure a good cleaning of the IAC well straighten her out. Am I right or should I look at something else?

Next time that happens, turn the truck off then back on. Mine was doing that and if i cycled the key it would straiten right up. Cleaned the IAC and it hasnt happened sense. "knock on wood"

I literally thought it died at one light because I couldn't feel it idle, looked down and it was at 250 but then it popped back up to 750. I just thought to myself is my gas gauge broken and I ran out of gas?
