help fouled plug ?
help fouled plug ? Have been having an issue with fouling out plug on #3 cylinder on my new engine.The first time I noticed was after car got tuned I checked plugs few days after and notice plug was sooted up including down in the tip so I replaced plug for that cylinder.Checked again and the same thing so I swapped injector to another cylinder to see if that was the issue and changed plug again.So I checked today and same thing plug is completely black.Is there anything else I should be checking.I only have this problem with #3.The car blows no smoke and compression is good and burns no oil.
