A customer told me his 'check engine' light went away after he replaced his gas cap
I was finishing up a brake job on a 2012 Civic in Phoenix when the owner mentioned it. He said he'd been quoted $800 for a new oxygen sensor, but a friend told him to try the $15 cap first. It worked, and the light stayed off for over three months now. It made me think about how often we jump straight to the big ticket items without checking the simple stuff first. How many times have you seen a shop miss something that basic?

Like @aaronowens said, always check the fluid level first before you let them sell you a flush.

That Civic story is a perfect example. I saw a shop try to sell a full transmission flush on an old Corolla for a rough shift. The owner checked the fluid level himself in the parking lot and it was just low. Topped it off for twenty bucks and it fixed it. Makes you wonder if basic diagnostics are even taught anymore.

Had a buddy get told his truck needed a whole new power steering rack because of a groan. He found a YouTube video, bought a $8 bottle of stop-leak additive at the auto parts store as a last ditch try. Noise was gone in ten minutes, just a leaky hose.
