Hello, my name is***** will assist you today.
When the motor fouls the plug, is it carbon fouled or wet fouled?
I take it that the plug is totally black when you take it out?
Do you do allot of ideling?
What oil are you using?
The motor actually calls for Premium plus oil.
Can you loosen the fuel rail off the studs and then have a helper turn the key on. Watch to see if any fuel is coming from the fuel injector as the pumps run.
You had fuel come out the rail with just the key on and not cranking the engine? Was it only on the bottom cylinder?
