Have you tried new Spark Plugs? Also after removing the plugs.
Take a paper towel and roll it up so it is like a long thick pencil. Stick that down the hole the spark plus came out of. Just to clean the moisture out. Also blow some compressed air down the hole.
Make sure all the moisture is out. The put the plugs in.
When you wash you car. Be careful if you wash the engine.
Dont let water get in to the plug holes..

weeeeiiirrdddd. i have a 2001 hyundia elentra gls, and my third cylinder is misfiring as well. my car also revs constantly on idle and in between shifting. it will flutter between 2-3000 or it will just stay at 5000. i replaced my plugs and wires to no fix with my cylinder. autozone also told me that it sounds like my throttle position sensor needs replaced, but every part they try to sell me will not fit and they swear up and down this is the right part...
