My GMC Sierra no longer accelerates smoothly because of the injectors:

Let’s give attention to the problems with the injectors in your GMC Sierra. If you have the feeling that your vehicle is sputtering, that it undergoes a loss of power, it is reasonably likely that because of a bad fuel quality one or more of your injectors have blocked or congested, which ends in a bad air/fuel mixture sent to the engine and which will consequently instantly disrupt its normal operation, bear in mind to examine the condition of your injectors.

My GMC Sierra no longer accelerate because of the clutch:

One of the basic triggers of a GMC Sierra not accelerating when hitting the gas pedal, or not moving forward, is that your clutch disc is outdated.

My GMC Sierra does no longer accelerate because of a punctured hose:
