Tyteg

ok my integra is having some serious issues and i need to know where to start with the repair here are all 11!! cel codes. where would you start?

p0108 map/baro circuit high input
p1259 manfacturer control fuel/air metering
p0137 o2 sensor circuit low volts (bank 1, sensor 2)
p0138 o2 sensor circuit high volts (bank 1, sensor 2)
p0141 o2 sensor heater circuit malfunction (bank 1, sensor 2)
p0420 catalyst effiecency below threshold
p0301 cylinder 1 misfire
p0302 cylinder 2 misfire
p0303 cylinder 3 misfire
p0300 random/ multiple cylinder misfire

and finally (pending code) manufacturer control ignition system or misfire


where would you begin to repair this car. if i replace the map sensor that will hopefully take care of the misfire and map sensor cel's and then i plan on replacing the cat, and the secondary 02 sensor. is there anything else i should check or replace? this is my daily driver and i need the car to be reliable. any help or suggestions would be great!
