The SES light came on in my minivan, so I pulled the codes and got a code
P0401, which, according to my reference means "Exhaust Gas Recirculation
Flow Insufficient Detected".
My question is where is the best place to start looking for the problem? I
would rather not just throw parts at it, but EGR problems are not my long
suit. Any help would be appreciated.
