Check your fuel pressure and check the code. Could be a TPS Throttle Position Sensor.

PO455 Evap System-- gross leak

Most likely need to have it smoke tested,
to find a bad hose or solenoid,valve.etc

You can get instant answers just putting any code into
google or whatever you use & print charts of codes

code 22 throttle position sensor low voltage
code 35 EGR
code 37 doesnt exist but im getting a code 37 also

Chevorlet did away with the inline fuel filter on the Silverado, so your truck does not have one that can be serviced or replaced like the earlier models had.
They have a "lifetime" filter/strainer built into the fuel sender inside the tank...I hope this helps.

we have a 08 1500 crewcab chevy that all the power door locks worked excepted the drivers door. We started to look at that door power lock actuater and now the passenger power door lock does not work. Could the trouble be something other than actuaters?

check switch connections,fluid level and actuator at transfer case if good have truck scanned for possible trouble code possibleas sensor or component going bad , some auto stores such as auto zone /advanced auto do it for free if theres a trouble code it will be a starting point

That is not a proper code ,GM trouble codes start with PO,
