While stopped and idling for a period of 2 minutes or more the truck begins to run rough and the check engine light comes on. Once I accelerate, the truck runs fine until stopped for another 2 minutes or so. The check engine light will clear once the battery is disconnected, but will return once idling for a period.
Codes given are p0171 and p0174; system lean on bank 1 and 2.
Actions: fuel pump replaced (needed it), IAC, ERG, PCV, mass air meter, air filter, replaced vacuum lines that were faulty, spark plugs and coil packs done, o2 sensors replace today. Engine light comes back on after a short drive, idle goes to heck after about 2 to 3 minutes of idle running.
Help please. Only thing left I didn’t touch was intake gasket.
have the same problem?
