Engine running to lean??

[NickSantagataa]

i hooked my truck up to a computer and it's saying its to lean could this be bad air line??

If there any air getting in between the maf and the intake manifold, a vacuum leak, or an intake manifold leak, it will cause it to run lean.

Okay thanks guess I'll have to find which hose went bad and fix it , this could cause to back fire correct ?

backfires are from rich conditions that put unburnt fuel into the exhaust and then it explodes....I have not heard of backfires for quite a long time.... mostly was on not cat emissions engines

Got it figured out... Wasn't paying attention when I changed the cool pack put wore 5 in the 4 slot the 4 in the 5 slot

that would definitely put unburned hydrocarbons into the exhaust
