The captain and I recently took her 2006 Carver 36MY out for a 5 day cruise in PNW. We experienced a couple of occasions where some low speed maneuvering (in the wind) requiring some throttle "blips", but coming back to neutral, killed starboard engine, and it didn't immediately want to restart/idle. I could bump throttle, restart, then bump throttle back down?

Some earlier docking lessons had similar scenario, that hadn't repeated before now?

After getting docked in Port Orchard for the night, and since no one was near us, I tried bumping throttles up then, immediately pulling to neutral, managing to now stall both port and starboard engines. Neither V/P 8.1L Gi-FF motor has more than 250hrs, but it is a 2006 with OEM parts. From reading numerous forum posts it would appear the IAC's are either sticky/dirty or failing?

My question, is has anyone recently tried the $35 units on amazon as they are listed as replacements for V/P 3843751 IAC, if so... are they junk? NAPA has #320177 IAC for $50, which would be my next step before paying $195 at Marine PArts Warehouse.

whats steps do i need to do without a scan tool? are there codes to clear on the V/P ECM, or just plug & play, codes clear on their own?

as always, thanks in advance for the insights and knowledge share!
