Hello, The check engine light is on, and has been on for a while, it seems to run great. I plug it in at schucks and the codes that came up were po171 and po120. where should I start with this. and is this something that could fix. Thank you for the help in advance...

Both those codes come up in a search.

Search "P0171" and "P0120" and do some reading.
