Default Plugs keep foiling up
After 50 or so miles the plugs are foiled up. So bad i had a hard time getting home tonight from a car show. I just got the car ,so have no history its a Roush 402 sr. So far change out the plugs , adj floats,trimming ,. When engine has fresh plugs engine runs real strong! Starts right up ,water temp is good, but when plugs go bad, back fires after let foot off the gas, here it missing,ect. Any suggestions..
