i have a 2001 225 efi that just started running rough if i idle a lot it does not want to come out of the hole and on top end the rpms surge like it is not getting enough fuel
From what you describe it sounds as if its loading up due to the recirc valves stuck closed or blocked. If you rev it up several times to clear it out does it still bogg planing? It also could be a injector/s problem...
if i rev it up it comes out of the hole a little bit better some times it runs fine then sometimes it acts like it dont wnt to get up to full speed i will lose 2 to 3 miles per hour
