What I have is a 1998 Volvo/OMC 4.3Gi. The engine model is 43FBPBYC. The problem i am having is when the boat is cold, it has a very hard time starting. What it does is if you leave the throttle in the neautral position, the engine will catch for a second and then die. If you try to give it any throttle it wont evn catch, like its choking itself out. Whne it finally does start running with the slightest bit of throttle, the idle is all over the place. After its running it runs perfectly. All day long you can shut it off and start it right up. This is only a problemn when cold. It acts like a sensor issue to me. Im just not sure which one? Any help would be greatly appreciated!
