    Default 2006 5.3 check engine codes

    hello im new to this site. curious if anyone has any suggestions. i have a 2006 1500 with the 5.3 and am getting the p0101, p0171 and p0174. these are for mass air flow sensor and both upstream o2 sensors. i replaced both o2 sensors and cleaned the maf sensor. truck ran better for a few miles then threw the codes again. doesnt have the power it used to and has some pinging on hard accelerationand. thanks for any info
