Car turned a code Car has been sitting all winter except for the 2 week start up and run till it gets up to temp all the way. The last time it turned a SES code. Had it checked P0400 EGR air flow malfunction. What needs to be done?

Maybe, maybe not. If the valve is not working due to the diaphragm leaking, then you would need a new valve. If the passages are just clogged up, you need to unclog them.
