4 Stroke stalls at Idle

[TUCKER1]

I have a 2002 115 EFI 4 Stroke that stalls at idle alot. I have a special set of plugs that were installed that are a match set for the new ECU that was put in to engine (Making Oil Issues). Should I try some fuel injector cleaner.<br />I have taken it out twice since winterizing it. Could it be that the fogging oil has gummed up the plugs ?<br /><br />Thanks

They changed the computer because it was making oil? What would a computer have to do with that??? Never heard of that approach before. Sounds like they're grabbibg at straws. <br /><br />Fogging oil doesn't foul plugs terribly often That should've burned off in the first few minutes of running. I'd be checking the vapor separator for water. There's a brass drain screw on the tank where the electric fuel pump is. If you remove that and water comes out, you might have water in your gas tank. But before it would collect there, it should collect in the fuel strainer. Check that first.

Thanks WillyB,<br /><br />I was having about 10 oz of milk being made in the crankcase, Mercury Marine ended up putting a new T-STAT, New Programmed ECU, and a matched set of plugs to go with it. (All under warrenty). It fixed the problem. I will check the fuel strainer and water seperator is there a product you recommed to add to my gas that will help with the 4 stroke EFI engine? It runs perfect add higher RPM's. <br /><br />Thanks
