P0171 help
 

my CEL came on today and it was a p0171 system too lean on bank one...can someone help me on what can cause this code

never mind i found the problem the vac hose on the air inlet tube came off somehow when i was driving yesterday

Yeah. Its a very common problem with our trucks. Make sure it isnt cracked or anything. Its not very exspensive.

do you know how expensive the part is...i might just go ahead and replace it
