Recently went to start my 2004 mercruiser 5.0 mpi, and it will start then immediately stall out. It will start and run with neutral throttle. Yesterday I changed IAC and that did not fix the issue. Any suggestions on where to look next.
Happen to have a serial number?
In your first thread you said after replacing the IAC and letting it run for 15 minutes it was fine, has this changed ?
Is this a new to you boat?
What was the part number of the IAC and where did you get it?
