Hey, other day used remote start. And as I walk up to car I notice the cooling fan surging. Not on off but spin and then spin faster. Happened for about 5 min...and went away. Later day same thing. Hasn't happened again (unless wife hasn't noticed and told me). It was NOT the idle speed fluctating. Tach remained at fast idle until it came down.
Thoughts? SUggestions? opinions?
thanks in advance
