Changing spark plugs - check engine light?
Need some advice here. I changed the spark plugs on my 2008 Outback, looking to save a little money on the 30K maintenance. It wasn't terribly difficult and the plugs seemed to go in great.
I started it up and it runs fine, but immediately afterward I started getting a Maintenance required light on and the traction control light is on.
The only thing I unplugged in the process (other than the plug wires) was the sensor on the air intake.
Can anyone offer any advice as to what might have happened here?
edit: the "cruise" light is flashing as well and the cruise doesn't work.
