The evap canister behind the wheel is most likely your problem if it’s damaged. You probably have a big ole vacuum leak back there.

Another possibility causing a rich condition is a bad intake air temp sensor. Looking at the codes again, you may want to go after the P0505 for the IAC valve. Problems there will make it hard to start. Do you have a scan tool?

Don’t rule out problems with the evap canister just because it has been that way for a while. Doesn’t make it any less likely to have problems.

There is a lot that can be wrong. Without actual data to look at there is no way to tell you what to do. Best to take it to the shop. But driving with that box smashed is likely part of the problem and not something you can just let go like that. You may have damage the catalytic converter, gained a bad vacuum leak and so on. Or could simply be the IAC. Along with 10 other things.
