I have codes u0073 u0123 u0124 u0126 and u0293. What's going on? Can I fix this myself?

Getting your car scanned at AutoZone fixes nothing and is literally of no help. You need professional guidance at a shop near you by a trained professional. Keep in mind that none of those trouble codes should cause a check engine light, and none of those codes are related to an evaporative emissions system leak which is what is caused by a loose gas cap. I would recommend having the codes cleared and driving to see if anything comes back.
