car has been fine but recently i had a few codes thrown.... first was for the maf and thermostat coolant censors....... fixed repaired both/ changed them out car ran fine for 20 mils or so then ran like poop again........ now ive changed the map censor on top of the super charger codes i have now wich is way more then the first time 2 codes p0101 2 codes p0103 p1182 p0068 p0171 still runs like garbage after changing all the censors.... ive taken off the throttle body and cleaned it what is the next steps i should take .......

 

mods are 3 inch exhaust drilled and honed headers k and n cold air intake

 

P0171 can be the intake , bad fuel, or boost/exhaust leak somewhere

 

checked my intake and sensor....... was leaking around the maf sensor fixed the seal and retightened still ran like crap unplugged maf sensor..... replugged in and startd up seems to run fine

 

When did u install headers and intake?
