When I brake to a stop. The car idle sometimes drops to around 600-700 and feels like a slight stall. Could this be the IAC?

I checked for leaks and nothing showed up. Recently Changed the Cap and rotor and wires. Nothing still.

Has anyone have this same problem?

 

braking is causing your alternator to work harder (lighting up brake lights). Idling at 6-700 is normal. You should have nothing to worry about.
