I hooked up my OBD 2 code scanner and it's giving me P0402 right now although there is no check engine light on. A little while back, i had P0411 which caused the check engine light to come on, but i erased it and it went away..or so i thought. I checked it soon after originally erasing it and it was still there. Today i just hooked it up again and it's giving me the P0402 code but not the other one anymore. If this actually is a problem and not just a glich, then how much are we talkin to fix this?

* P0402 EGR Flow Excessive at Idle

* P0411 Secondary Air Injection System Flow Improper.

if that helps i dont know what it would cost but thats what they are

Are you rollin' stock, or have you modded your engine/exhaust?
