Default Pulled some codes today...

The code history said...
DTC P0400
EGR Flow Malfunction

Current codes

DTC P1415
AIR System (Bank 1)

any idea what could cause this or what to look for? Car runs fine but check engine light has been on for a week. Today I was sitting in traffic and I switched lanes to get into the turn lane so I goosed it a little to get ahead of the traffic and the check engine light started to flash, but then it stopped. Car didnt seem to run bad but I take it it didnt like that for some reason. It was hot out, close to 100 but I dont know if that would have caused anything.

Steady SES = emissions code. Flashing = misfire condition. Check all of your vacuum fittings. I don't know if an EGR or AIR system malfunction can lead to a misfire, though.

Yeah, I know the steady is usually emissions , and Im assuming my EGR is toast but I hope not.
