Fuel filter was changed couple thousand miles ago. You have to remember though if it was a clogged fuel filter all cylinders would be running lean, not just one. Also i last replaced the plugs about 6-7k miles ago. I have a new set up plugs on the way that i'm going to throw in friday. I checked the resistance of the plug wires and they all turned out fine. Visually they look fine too. As far as the distributor i opened the cap and it looks brand new, not a sign of corresion or build up. I'm not going to change the distributor mainly because the problem seems to be fuel related and only is happening in one cylinder.
