The only question I had was would that cause it to misfire, then go away after it cooled down? Because every single time it has done this, sitting overnight or for a few hours causes it to go away.

Do you guys have a good method of cleaning them? because that wouldnt be a bad idea anyway. They are cheap enough new if you get them shipped but Id like to determine that was the problem by cleaning them first.
