Pro tip: Stop trusting the computer for every check engine light
I've seen too many good parts replaced because of a vague code. Get under the hood and actually look before you start swapping stuff out.

Unbelievable how often that actually happens.

That point about not trusting the computer for every check engine light is so true. I used to just scan the code and buy the part it suggested. Then I wasted money on an O2 sensor for a code that was actually a vacuum leak. Like @lilyross said, it happens all the time. Now I always check the simple stuff first, like hoses and connections. It saves so much time and cash to actually look under the hood before throwing parts at it.
