Run rich at cold start only for 1 or 2 min Black smoke,missfire and engine stall

P0172 and p0175 , fuel system rich bank 1and 2 Mil on only 1 time in two weeks !

TRY CLEANING MASS AIR FLOW WITH PROPER CLEANER AND MAKE SURE THERE ARE NO AIR LEAKS IN FRT ON THE SENSOR.IS THE AIR FILTER CLEAN?

Everything was done ,brand new air filter and maf was cleaned with maf cleaner !! I'm realy confused because the trouble was only for the 2 first minutes on cold start

READ LIVE DATA WITH A SCANNER TO MAKE SURE ITS RUNNING RICH STILL

Fuel trim long term it's -30 And and the snow was black 2 feet long behind de truck !!

ARE THE O2'S READING OK.DID YOU BUY A NEW DELCO MASS AIR FLOW SENSOR OR REBUILT?

O2 works great and i don't buy any parts yet !!! I work for dodge dealer sinse 15 years and i'm not familiar with this system !!!

READ YOUR MASS AIR FLOW SENSOR DATA AND CK FUEL PRESSURE WITH FUEL PRESSURE REGULATOR PLUGGED INTO VAC AND UNPLUGGED.SHOULD BE APPROX A 10LB PRESSURE DIFFERENCE.IF NOT START BY REPL REGULATOR.CK TO SEE IF REGULATOR IS LEAKING FUEL ALSO

Ok ! But do you know the normal air flow spec number at cold start ?
