I put 60,000 miles on a Jeep with a check engine light. Also spent thousands on trying to fix it at various shops which would replace all sorts of things, to no effect, including about 5 attempts to replace a costly computer board.

Eventually had a redneck guy working out of the back of his pickup truck have a go at it. After hearing about the history he spent hours unplugging, cleaning, and replugging every single wire connection and socket. And the light stayed off.

Are you sure he didn't just leave that particular light unplugged?

It's a good idea, but such a ruse would be easy to catch. A properly-wired check engine light illuminates whenever accessory power is on and the engine isn't running: i.e., right before you start the car, every time you start the car.
