fuel rich
ok guys i have an 09 1500 and i got a couple of codes after i did a simple filter switch.
i got p0175 and 172 when we checked the codes it said it was running rich. now my truck has only 4,000 miles on it i dont think its the o2s but we never know.
second all the intake and spacer are put on correctly checked twice.
the only thing is that i was -12 and -16 on both trims at idle.
the codes after the re tune have gone away dont know if i should still clean the maf or wait for the codes to come back then clean it. any advice would help.

i would think so
it was tuned a while back with my 1st filter the volant power core, which i thought was to restricted then i swapped it out for a k&n brand new at the box no excessive oil and about an hour later it the codes went on.

after i got it checked the codes went away then i had it checked by my tuner and re tuned to high octane since there was a misunderstanding the 1st time and truck felt better plus the drive was at least 10 miles and no code appeared.
