Default Could use some help with codes
Hey guys i pulled two codes from my truck today and was wondering if any one could help with them. I have an 03' 4.6 V8.
The first code was P0171, follwed by P0174

I would appreciate any help with it.
Thanks guys

Check for vacuum leaks in the intake and clean the MAF & throttle body.
