A FSM? Full Service Mechanic? Could be a liar and a thief a screwball. Sadly, that is my experience with too many FSM and car shops. This is why AutoZone, NAPA, Oreilly, Rock Auto and Amazon are working at full vigor! Ask me about my $511 fuel filter and car shops. Dealer too! Cheers!A FSM is a more useful than hoping it's done right on YouTube LOL.
