Hope you're okay. Sorry about your wreck but it's cool you got a new hatch.

Code 1 - check that the wiring is nice and tight with no kinks and or breaks. The slightest disconnection will cause a code...

Do you have a system? Code 20 Electrical overload could be due to something straining your whole electrical system. This could also cause your rolling idle effect.

Code 17 - VSS. Does your speedometer work? Make sure it's plugged in all the way at the tranny.
