Question

strong texthow can I fix and I was told to change plugs and coil pack....is that something I can do myself

Answer 1

You should start by replacing the spark plugs for the misfire codes

P1793 is for the wheel speed signal, you can try to reset the code and see if it comes back, if it does I would try to clean the wheel speed sensors (since they are magnets and can correct dirt on them and metal)
