I have a '98 37DA with 8.1 Horizon engines. port engine runes fine, reaches max rpm. Starboard engine idles surge, sometimes stalls, cruises ok. but can't reach max rpm. after investigating plugs, wires and distributor, fuel pump etc. have come to the conclusion its a sensor. It's a FI engine so I know they have sensors to control the air/fuel. Thinking it has a MAS sensor behind the spark arrestor, I was surprised to discover it has none[???]. Where should I look and what am I looking for?
