From what i know the 302 is caused by the 401.....leading from there I have checked the feedback hoses, they are in good shape, not clogged....from there I changed the feedback sensor....I am not getting a 1408 code.....so this leads me to believe that it is the EGR Valve....just looking for confirmation........any ideas??

The P0401 is fir insufficient flow for the EGR. As Hammer Time stated, please post the year, make, model and engine size and we can help more. Being way2old is why I need help from younger minds RebelRoze New User Aug 8, 2012, 9:13 PM Post #4 of 5 (2362 views) Re: EGR DTC code> Need assistance Sign In My bad.....I had it in there and the page refreshed....the vehicle is a 1999 ford windstar 3.0 L Hammer Time Ultimate Carjunky / Moderator Aug 9, 2012, 3:24 AM Post #5 of 5 (2355 views) Re: EGR DTC code> Need assistance Sign In You can easily test the EGR valve with a hand held vacuum pump. If it's not the DPFE then i would suspect a plugged passage in the intake. I doubt the misfire has anything to do with the EGR problem. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
