Motor - 1997 Evinrude 175 HP V6
Hello all,
I changed the spark plugs in the motor and when i take the spark plugs out all of them but top right plugs are blackened. The one in the top right looks like it is a brand new plug and i can only assume that the cylinder is not firing which would cause the plug to look this way. Other problems i have is... The motor has trouble starting, the motor dies at idle, and during low rpm 1500-2500 cruising you can really feel it missing. However during high rpm cruising 3000-4000 i don't really notice it.
Any ideas on what could be causing this or things i should change?
