Hi, welcome to Just Answer.

This code indicates that any one of the following items can be at fault.

Fuel pressure/pump, injectors, EVAP canister purge valve, EGR system, HO2S, intake/exhaust system

To find the fault one will have to test each one at a time.

One also need spacial tools.

If you would like to do the job yourself I can elaborate further.
