Try cleaning your Mass Air Flow senser with cleaner from part store make sure it's for that senser n clean up throttle body real good with cleaner too. Also change out your PVC valve. I also had cooling fans not coming on as needed replaced couple relays n all is good now. Also check temperature control senser. Had same problems. Truck runs so much better now.
Best answer (according to Expy)
I ended up changing fuel pump and fuel pressure sensor the 1 on tank ran good for a week rite back missing barley would stay running at all disconnected mass air flow sensor not a problem since and getting better gas mileage than ever 16.8 to 17.3 interstate
