those are the codes my truck has been throwin. it started off just thrown P0172 but now its thrown both of em. accordin the the other thread its the fuel trim system rich. i dont know what i should do about this? what exactly is it and how can i get it to stop?

 

if it is both banks i would check the fuel pressure regultor, make sure the maf is clean and the air filter isnt restricted.

 

i got a airaid air intake but it runs of the stock mass air sensor and a throttle body spacer... whats the MAF?(mass air filter?) and where can i check the fuel pressure regultor? thanks

 

MAF=mass air flow sensor
do u have access to a fuel pressure gauge?

 

the gauge thats on the dash reads that its fine

 

what gauge?

 

idk wat the fuel pressure gauge is

 

it is not a factory gause on the dash, you hook it up to the fitting on the fuel rail to check fuel pressure. if your not to mechanically inclined i suggest you bring it in to a qualified person.

 

thanks man. ill go get it checkd out

 

its showing your rich your o2 sensors are doing there job check you throttle body and make sure its clean of carbon make sure your air intake isnt pluged up even inside the fender and your mass air flow sensor is in the bottom of the airfilter jug get some eletrical cleaner and spary it down dont use brake clean hope this helps

 

i fixd it my air filter was leakin
