First thing I would do is clear out the computer and give it a fresh start from the beginning.
Second thing is make sure you're not on your first few tanks of gas still because it could just be the lack of quality gasoline that the truck doesn't like. Also, check the air filter because a dirty/clogged air filter can wreak havoc on the air/fuel mixture. Next, take the air hat off and see what the throttle body looks like because it could be it just needs a good cleaning!
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
Start but do not hit the throttle. Idle for about 10/15 seconds then turn off.
Restart the truck and drive as usual. It will take at least 12 starts and 48 miles to fully retune the computer.
Hard Codes leave a shaddow for 40 full cold starts.
