Well the P0456 code wasn't a big deal. I did have to get the gas cap replaced, but that was only $20.00 or so.
We also found that my right-rear caliper was stuck closed. This was causing the car to act like I had the parking brake engaged since yesterday. Because I kinda did. The cold weather just made it more obvious.
I had the mechanic show me how to unstick the caliper, and that should carry me until I get all the brakes replaced in March.
I also have a leak in my oil-pan gasket. It's a small leak but it's annoying. That work will have to wait until March as well.
