I have a misfire on moderate acceleration. It's a Mercruiser 260 Chevy 305 (5.0L) with Bravo 3. It shows no codes. I can accelerate easy or WOT and it runs fine. Moderate acceleration and it misses badly.
I replaced the IAC module and fuel pump last season. They have about two hours on them. Plugs are under 30 hours.
Suggestions? Throttle position switch maybe?
