DTC - 22 Throttle position sensor error (signal low), is tps connected?
DTC - 23 Intake air temp sensor error (low temp indicated) check and make sure the sensor is connected
DTC - 43 Knock sensor error, ignore this for now, will not cause rich run.
DTC - 53 System voltage too high, check reference voltage from PCM, it should be around 4.5 Volts, this could be the cause of all your problems, the computer will need to replaced almost for sure.

Depending on how many miles are on the car, I would bet you have a stuck or failed fuel injector, or multiple injectors that are leaking. Check EBAY, there are usually lots on there for sale used. They are very easy to change.
