P0107 is a MAP sensor low voltage code
P0405 is a EGR sensor A low circuit code
P1404 is a EGR stuck open code
P0442 is a EVAP small leak code
P1635 is a A/C, MAP, EGR voltage out of range code
If the car is bone stock I would start going over all the wiring harness and make sure it's all in tacked. Also check for vacuum leaks. Then start to bench test the MAP and EGR sensors.
