If memory serves me, 102 is MAF, 404 and 405 are EGR and 442 is for sure EVAP.

Thank you all, but I was wondering if you all could think of some wire/fuse that they all lead to? I have replaced all parts with OEM spec and the codes are still there. Trust me, I've gone through everything.

This is a stupid question and I mean it in the nicest way....... I promise... But you are "clearing the codes after the parts are being replaced right ? Dumb Question I know.

Check the electrical connectors at each part if they are bent over sharply or length restricted it could cause bad connections
