Computer problem
2007 Buick La Crosse Two Wheel Drive Automatic

Hello, my question is, would not changing the air filter for two years cause the check engine light to come on.

No, unless it is so clogged that it is causing a misfire or a very rich mixture. Take the car to a nationally recognized parts store and have them scan the computer to identify where the problem is coming from. Most will do it for free.

Let me know if you have other questions, let me know.
