The current fix could be super simple or it could require major internal repairs.

 

Inspect the current issue and see which way you need to go. It could be as simple as a $8 spark plug or needing a new spark plug wire or coil pack. Worst case is that the lifter is being a problem and that would mean removing the cylinder heads to address the issue.
