I told this story a while back, a guy I used to work with is my mechanic. He’sa certified mechanic and is the mechanic for five lumber yards which is where I met him. I had an issue with my truck, he was three weeks out so the wife took it some place else. They quoted her $800 for plus, wires, coils, and plugs. Luck would have it my mechanic has a cancellation and got me in. He went through the diagnostic process and determined it was a burnt valve, not just in need of a tune up! About the same price, but I asked him who’s responsible for payment on a misdiagnosis? He said I would be. The saddest part of this is the place my wife took it to, is the most popular shop in town, it’s not a chain store, it’sa mom and pop shop but still it’s pretty scary for sure! I told him he can’t retire!
