Please refrain from posting questions in the wrong section.
For one you'll get your answer alot quicker.

Another tip is to post as much info as possible. Do you have a check engine light when the misfiring starts? Did you get it scanned? What was the code, what was the description of the problem on the scanner?

You can also type the code into the Search function and you may get the solution you're looking for.

EDIT:

If you're throwing a CEL, get the code scanned at Auto Zone or similar and follow the links in this list: https://blazerforum.com/forum/showthread.php?t=45945
