5.0 MPI hard start running rich

[rob954]

Hey Guys, having an issue with one of my motors.. its USUALLY dies at idle and i have to give it a little bit of throttle to get it started, sometimes it will stay running at idle and other times it will die ( see video below ) . I can smell that its running really rich and can see very faintly some smoke coming from the water (its in a slip) .There seems to also be a slight loss in power, however if i crack the throttle enough to get to about 600 rpms it seems to run fine.. i just changed the cap, rotor and IAC but there is barley a difference. plugs and plugs wires were done maybe 2 years / 20-40 hours ago. oil looks good, engine doesnt overheat...hopefully someone can look at the video and give me some insight... THANKS IN ADVANCE!

Check your fuel pressure, if it's high you probably have the CF3 paint problem

I don't know what years...... but there is a little filter in the carburetor/flame arrester that could be gummed up.

Don't know if I read it on CSR or on the SeaRay owners Facebook page.

I think the little filters are about $2 and it cures a bunch of running issues.

thanks for the reply's guys , will head to the slip possibly tonight after work.. i hope its not the pump, i do remember seeing the little filter and it was black, i also noticed some kind of black build up on the throttle plate, im hoping its just a filter issue.. will report back with my findings
