exessive flow. EGR valve. I have changed the EGR valve, the throttle position sensor, the mass air flow sensor. From reading some of the threads I will try to clean the small tube coming from the EGR valve. Man I hope this works. Renewal time is coming to a close and I can't get the light to go away! Codes are:P0402 and P1404. Thanks for any help.
