I have a 2001 Ford Escape V6 3.0L. When it is cold started, it wants to stall but when it is warmed up for a while it is fine. I already changed the EGR valve and the DPFE sensor and no luck. Changed the spark plugs and the oil the other day and now the engine light came on with 3 codes, P0171, P0174 and P0304. I was wondering which I should change next, the Idle Air Control (valve)Unit, or the Mass Air Flow Sensor??
