Still having problems with codes 171 and 174!

And the truck is a '03 with the 4.8. Doesn't bog under throttle at all. . . Just idles bad sometimes, and other times runs like a champ.

if you use OEM dealer gaskets, they always do the job.

Thanks for the help guys! Gonna tackle this pretty quickly. Saturday morning hopefully.
