Depends on how bad the piston is. I would ask you what the symptoms are that has made you feel the problem is a piston. It might be something else. Pistons don't usually give trouble in modern engines but all sorts of other things do. If the engine is misfiring then it's almost certain to be something other than a piston - maybe fuel system or electrical system.

How do you know if the piston rings in your car are bad?

Worn piston rings will cause your car to burn oil. It will smoke, and you'll have to add oil frequently. Additionally, the performance will fall off as compression is lost past the worn rings. There may be a "slapping" sound as the piston skirts slap the cylinder walls, and this will occur in cases of advanced ring wear.
