Maf

What is the way to test these? I think mine died today,I get codes 157,158,173 and 177 and it won't stay running unless I keep throttling the truck.

That sounds like a MAF, usually they only run for about a few seconds and die. You running a K&N?

No K&N, all factory.
If I unplug the MAF I can keep it running

Well then I say it's the MAF. Those K&N's, though some people claim they don't , can ruin the MAF, and cover your intake in a pink oil. I pulled mine out and threw it straight into the garbage after finding my intake tube covered in the stuff.. Bought a 5 dollar micro gaurd. Frams, and Fram Air hogs aren't great either. Sorry about that. Good luck on the replacement.
