Hi All,

I am having a problem that I cant figure out?

1996 Volvo Penta 5.7 GLI (yes there is a GLI model) TBI

I have taken the boat out several times and between 1.5 hours to 2 hours it runs perfect. Right around two hours the engine goes into SLOW mode and cuts one injector off and cant get over 2500RPM. I bought the code tool and hooked it up this weekend and received the following codes:

14:Engine Coolant Temperature sensor circuit
33:Manifold Absolute pressure sensor circuit
42: Ignition control circuit
43: Knock Sensor


Can all of these be bad? I am thinking about clearing the codes and running again and as soon as I have the problem again Run the code tool? Any help appreciated!!
