I recently replaced the IAC valve on my 2005 crownline, it's a mercruiser 305 fuel injected engine. The first time taking it out after changing it i noticed that when you first start it up and begin idleing slow when you start giving it gas it hesitates for a minute, like it's not getting gas and it's goin to go dead. But then it will pick up rpm's and run fine the rest of the day, even stopping and starting. It's like it is losing it's prime. Any suggestions??? Anybody.
