Code 24 - Vehicle Speed Sensor or Circuit; Code 33 - MAP Sensor circuit error (low vaccum); Code 45 - Engine Rich Condition; Code 55 - Fuel Lean Condition. I would recommend taking it in to a mechanic as you likely have multiple issues that need to be repaired in order to fix all of your codes.

Any driving/idling issues? Why did you run the codes? Give us some added info and maybe we can be more helpful. Maybe your cat converter is failing or one of the main sensors in the fueling system is going bad.
