94 Accord idling high
 

Got a 94 Accord,2.2L with manual trans.Engine rpm's can race to 2000
when engine is hot and while driving in stop and go traffic.Seems to
coincide with the warmer wheather and air going into the throttle body
as it seems to be fine while highway driving.I know the IACV is
working properly when first starting the car but can it stick when the
engine is hot?Map sensor?~thanks
