I have a 2006 Chevy Aveo with 207K+ miles, standard transmission. The car normally idles around 800rpm. Recently, when I have a lot of accessories running, (lights, fan on high, wipers, etc) when I slow down to come to a stop and push in the clutch the idle drops to around 500-600 rpm and then recovers to normal 800 rpm within a few seconds. It only started doing this recently. With no or low accessory load this doesn't happen. Other than this the car runs perfectly.
Any ideas?
Could this be a failing IAC valve?
