Hesitation during acceleration in your 1994 GMC Sierra could be caused by several factors, including a clogged fuel filter, a failing fuel pump, or issues with the ignition system, such as worn spark plugs or faulty ignition coils. Additionally, a dirty mass air flow sensor or problems with the throttle body could also lead to poor acceleration. It's advisable to check for any diagnostic trouble codes and inspect these components to identify the root cause. Regular maintenance can help prevent these issues from arising.
