Nope it doesnt have an aftermarket cold air intake.

 

with the truck in park and engine on, slam on the gas and look at your tail pipes.
If a puff of black smoke comes out your truck could be running too lean

 

So I just started it up again and revved it a little. At first it started to hesitate a tiny bit when I let up off the accelerator and the idle became a little funky but bounced back to normal. I started revving it some more and it seemed to rev up okay. I thought maybe it could be my EGR valve, but I see that whoever owned the truck before, cut the hose, and stuck a bolt in the line.

There was no black smoke. Could it have been that maybe my fuel pump was overheating from having low gas? I ran it for a total of maybe 3-5 minutes today.

 

you wont know the answer to your question until you fill up again.

Filled up a 5 gallon gas can and dumped it in the tank. Started the truck and revved and idled it for about 10-15 mins. Then I drove it up and down the block about 4 times and then around the block once. It accelerated smoothly like it always has with no hesitation.

Could it have just been low on gas?

 

thats what it seems like to me.
