My Ride: A Car
CEL on!! I stopped by a shop and told them to pull their OBD2 out for me. Looks like it's only a thermostat 
Thermostat 1 11537586885 $109.72
Gasket ring 1 11531440192 $5.97
Not too bad. I can live with it. Parts prolly cost me $80 or so after discount. Hopefully I can get my friend to program my car and switch out the thermostat and ALSO take care of the airbag recall.

I don't get why a bad thermostat will show increased emissions....
If the thermostat is stuck in the open position, coolant will flow the second the car is turned on, so it takes a lot longer for the car to warm up. During this extended warm-up time the engine releases more emissions, which gives you the emissions warning.

When the car starts, the thermostat closes the valve to the coolant so the engine can heat up quicker. A warmed up engine has less emissions.
