Just had an oil change and had my air filter replaced..now my check engine light is on..any ideas of what could have set it off? could the changing of air filter have triggered this?.. thanks, J

You may want to check the wiring connector on the airflow sensor as well as the tightness of the clamps on the hose from tha airfilter itself.

what next2pool said. You might also want to check into a code reader. It comes in handy and these cars throw a bunch of codes, plus it can be used on others. It's a tool that will get use.

Yea swapping the air filter is tight and a pita, one of the major reason I went to my Volant. Make sure the clipped it in and the lid is tightly on the box as well as the IAT and MAF sensors are plugged in properly (IAT isn't on the N* but maybe on the V6 idk)
