Why does the GMC Sierra struggle to accelerate?
Years 2014-2018

Answer

If our GMC Sierra has trouble accelerating, for example hesitating when you step on the accelerator pedal, it means that there is a malfunction in the fuel system. In fact, it could be a blockage of the fuel filter, the air filter or the EGR valve, or a problem with an injector or the fuel pump. To promptly identify the malfunctioning element, it is advisable to go to the workshop for a check, where the errors recorded by the control unit can also be read.
