Time string? Do you mean the timing belt? 100-140 miles is a good rule of thumb. Definitely have a pro do it though, things can get tricky on a truck that new.

Hello. Welcome ot FixYa. Please allow me to assist you.

The P-0171 code indicates, in most instances of this code being set, a dirty Mass Air Flow sensor.

This sensor is located in the pipe between the air filter box and the throttle body.

What I would do: Locate the sensor, remove the wiring connector, remove the sensor, and, with some commercially available "Brake cleaner" (a spray can), spray the interior of the sensor until it is clean. Do not use compressed air, as the pressure can and will damage the sensor. After the sensor is cleaned by spraying the brake cleaner in it, reinstall the sensor, hook up the wire connector and drive the vehicle. The computer will see the sensor reading the correct amount of air flow, and the light should go out.

take the vehicle to AutoZone and have them read the OBDII code in the computer so you actually have some idea what might be wrong instead of guessing

In the front, place your jack stands on the stabilizer bar bracket that is bolted to the frame...
in the rear, put the jack stands on the rear end, closes to the outside as you can get...
Hope this helps ??

check the bulbs or the sockets for damage
or the wrong bulb
you are getting feedback through the wiring
and that lights up the dash

Replace the entire switch, not just the tumblers. Before installing the new switch take it to a locksmith along with your old switch key and have the new lock keyed to work with your old key. This will save you from having a different key for the doors & switch.

You lossen & tip up the bed, if you
don't want to drop it down

Best guess is its a fuel delivery issue. I would check the fuel pressure to make sure it is within the range it is suppose to be. It could also be on the return side. A bad fuel pressure regulator could cause the system to have low fuel pressure. Before pulling the pump or anything get under it and pitch off the return line to the tank. The pressure test the system again. It should almost double like from 60 to 100 lbs of pressure. Those are gm numbers so dont look for those exact numbers. If it does not have the increase like i mentioned then the regulator is bad.

This means the computer has detected a problem with your vehicle. Take it to Autozone and they scan it for free for you. They will let you know what is wrong and what you need. Thanks for choosing FixYa.

Don't expect any help on a 11 year
old vehicle, even with a recall

The speedometer cable may have broke or rattled loose.

Could be your starter. If you turn it and it doesn't crank, should be the starter.
