Hopefully i cam get pointed in the right direction..... I have a 2003 Expedition with a rough idle once it warms up! When first started it is fine. After about 5 minutes it idle rough and has a bad stumble when i snap the throttle.... The check engine light is on and it has p0171 P0113 and P0201 ive checked for vaccum leaks havent been able to find any and the intake gaskets were replaced late last year
