Your check engine light is on. AutoZone just handed you a free code that says "misfire." So naturally, you are ready to throw a set of spark plugs at it and call it a day. What could go wrong? Besides everything.
That free code is like a weather forecast saying "it might rain." It doesn't tell you if you need an umbrella, a boat, or an ark. We wrote an entire blog post explaining why we charge a diagnostic fee even when the parts store works for free. We talk about our $5000 scan tools, the technician who knows your engine's secrets, and why guessing with your wallet is a dangerous game.
If you live in O’Fallon, Missouri and you want the problem fixed right the first time (backed by our 36,000 mile warranty), click the link. Read the truth. Then come see us at Hillside Auto Repair. You have free will-choose professionals please!
