I have a 2002 225 hp evinrude ficht. It will not idle . I can crank it by pushing hotfoot half throttle,cranks and runs fine but when i let off gas to put in gear it goes dead. I have put 2 sets of plugs and indexed. My mech found oil leak and fixed under flywheel. I have tryed a known good throttle pos. sen. . My mech thought it must be the emm. I sent it to dfi technologies. They tested it and said it was fine. I have a beautiful 2003 ranger 520vx with a 225 that I have not been able to use since the first of march. Going mad !!! can anyone help please
