So this is weird and crappy. I changed my Donaldson air filter (oem replacement) on Friday. I drove 7hrs to VA and parked the truck.

The next morning I started the truck and threw the above code. I popped the hood and noticed that dumbass=me missed on tang on the air box lid.

I checked the filter fit and put the lid back on properly. It threw the code again. I went to an auto store and bought maf cleaner. That didn't fix it either.

For the last two days the code comes on shortly after startup. I clear it once im driving down the road (otherwise at idle it comes right back on) and it stays off until I shut the truck off and restart.

Any ideas? Bad filter? Bad maf?

Thanks!

(Re-check again) Make sure the air filter itself is installed correctly. Take it out & put it back in. The time I used a Donaldson brand air filter, I noticed its harder to put in, cause it fits a bit tighter in the air box vs the AC Delco air filter.
