Not likely.
Diagnostic code(s) would point us in the right direction. Your local auto parts supplier can scan it, but they tend to be less than reliable. A GM dealer, or any competent shop would be a better choice.
Meanwhile, we can work with what you do know:
You have a misfire. How often? At what speed? Is it always the same cylinder, or is it random?
Does it occur under load? Cruise? Decelerating?
When it is cold? Operating temperature?
How often have you filled the gas tank?
