Could also be faulty fuel injector for that cylinder. Might try some sea foam in your gas tank. This will clean your injectors.

Dandy's right, check the fuel injector for cylinder number 3. If it checks ok, compression test that cylinder. Could be a valve problem. HTH. -Jim

The valves are located in the head. HTH. -Jim

The valve is an internal part of the head. Not something you can see without tearing the head apart. I do not advise that. But having a compression test done will tell you if it's operating properly and is not that hard to preform.

Swap the #3 fuel injector with another one on the engine to see if the miss moves with the fuel injector. Putting Seafoam in the tank will not clean an injector that is not passing fuel. When you get it fixed run some Chevron Techron fuel system cleaner once or twice between oil changes to help keep the fuel system clean.
