Just had a user unfriendly piece of metal hit the thumb bone, that's why you'll notice 80% of mechanics HATE FORDS!!! Still get fiberglass in your lungs from their cheap heat shielding,in the arms(front grilll area), various deep cuts from razor sharp plastic radiator fans,underdash plenums, sharp sheet metal everywhere,lets not get into those needle size wires in the E.G.R. tube shielding. But I'm an auto electrician so that's my main issue, and why do you stand in traffic to check the oil, G.M.'s are ALWAYS on the right. Their diagnostic tree is designed to sell parts.
