check your in-tank fuel filter: at speed debris turbulates inside your fuel tank and, can block the fuel pump inlet then fall off again and, your truck will operate well untill you speed up again the culprit is most often the fuel pump fishnet filter

Im not sure where your from and if you have these places in your area but this may help you. If you have an Autozone or O'Reilly you can take the truck by one of them with the light on and they will hook up a computer to pull that code. They will then tell you what the code means and you can go from there. I hope this info helps you out and have a great weekend,

The EGR and the lift sensor may look perfect from the outside but the under side of the EGR valve and the EGR passage (small tube) are the REAL WORKING parts.
The carbon inside the EGR passage tube and the underside of the EGR valve must to clean out.
Make sure you has a NEW EGR gasket before you start the job.
It's a 2-3 hours job.
If you do not clean the EGR passage tube the Nox emission will get higher (check you past emission reports).

First. Check the vacum routing from the egr. facing the engine, the vac.
line should go to the right and connect to the egr vacum regulator
solenoid. The line from the solenoid to manifold vacum. The solenoid
is also connected to the powertrain ctrl. module And some models,
have a egr sensor. the two vac.lines from the sensor(if equipped)go to
the exaust below the egr valve. The three wires from the sensor go to the pcm. At this I would plug in the obd2 scanner if no vac.leaks or
bad connections have been found. This can narrow the field greatly.
You can stop by an autozone/napa etc. they will scan it for free.
I hope this helps. Good luck.

If you are sure the valve is working and the passage is clear....it should stall the engine when you put vacuum to it while idling, then you may have a bad MAP sensor. There was a problem with them on this year. Sorry, I don't have the specs for the modulator with me, I'll try and dig up some info later today. The reason I said MAP sensor; the computer uses the signal from the MAP when it runs the diagnostic to check EGR operation. I'll add to this solution later today, in the meantime, does applying vacuum to the EGR stall the engine? If not, you'll need to remove it and clean out the intake manifold.
