Hey guys I have a 1997 Ford expedition XLT 5.4V8. The code P0401 keeps popping up I have replaced the EGR Valve, EGR solenoid, DPFE sensor and several hoses I was told recently by ford they believe the system is clogged and they want like $600 to take it apart and clean it. has any one ever heard of this and knows a better way to get it done.
My only issue is when at cruising speed and the lift the throttle off slowly the truck kind of rocks and hesitates and once and a while at idle you hear something like a slight misfire, I have 8 brand new busch plugs, 8 new accel performance coils, Gibson shorty headers, K&N cold air intake, Edge performance programmer, new throttle position sensor, new IAC valve and several other components replaced. Any ideas or help would be awesome thanks.
