Hello again guys, im having an issue with my 7.4 mpi. Ive only had the boat for a few months and it runs very rich a idle and very lean at wot. I ve played with fuel pressure enough to get it to richen up at wot but of corse that doesnt help the idle mixture being so rich i get fuel and soot out the exhaust. I thought perhaps the injectors were clogged so it took the out and individually cleaned them up good but that hasnt helped. Im now wondering if the map sensor ( still in the manifold) should be relocated somewhere where boost isnt present like in the intake pipe. Vin L354355. Enging has been rebuild with high compression forged pistons.
