I have a 2005 Silverton 340 w/ twin 8.1L crusader 496 engines. They have fresh spark plugs, new fuel filters (but not the little inline ones) and low hours. Stbd engine falls off at about 3,000 rpm. It is strong up to this point w/ both throttles about equal to one another as you run it up. Then the port motor keeps going and the stbd acts like it won't take more fuel. It is not loading up and smoking, I can't tell that it is missing either. It acts like the throttle just stops advancing - very strange. Then after you run for a while during the day, it might take off and run perfectly. I have no idea what could be causing this issue. I just installed new plugs and nothing changed. Has anyone ever had an issue w/ these engines like this? Could it be something w/ a bad fuel injector? I get no check engine lights at the dash either. Thanks.
