Hey guys,
Would anyone happen to know what this might indicate? Some mornings when I start my car (in the garage), it starts up but about 2 seconds after starting, the RPMs sort of dip down a little bit and then return to cold idling speed (2,000 to 2,800 RPMs). What does this mean? Could it be the water pump? I have a 97 with 130,000 miles and, I believe, the original water pump. Should the water pump have been replaced by now anyway?
Thanks!
Chad
