I just got the truck last week and when I drove it I thought it need a tune up. but come to find out that #5 plug was bad.
would the intake cause this?
what about the oil? it has 5w-30 and the truck has 147,000
should I change the oil to 10w-40?
please help, has this happen to people
it is a 5.7
can post pics of the plug later
just to add the truck does smoke at all.
