trucks shooting p0171 p0174 p0327 p0332 and p0151 and i have no idea why
see if this will help http://www.aa1car.com/trouble-codes/
otherwise I would take it to a shop and see if they know what's causing the codes to come up.
Thank you appreciate the help
This is just a guess but if I read your codes right your running lean and having knock/ ping. It sayd your O2 sensor is messed up. That can change your fuel mixture causing a lean condition. Which in turn would cause the pinging/knocking. Obviously this is just my guess though...
