I keep having two of the spark plugs on the drivers' side foul out on me. When the plugs are new, the car drives great! It idles great! Everything is perfect. But the plugs foul out with carbon every time. Its only the two that are furthest from the distributor. I replaced the distributor, the ignition coil, and my spark plugs and it still keeps happening. I have began to think that an intake manifold gasket leak could be causing my problem, however I am not totally sure. Are there other issues that could be causing ONLY 2 of the spark plugs to foul? I checked the other ones and they seem fine!

Have to done a compression test? With a vehicle of that age you may be leaking oil in the combustion chamber which may be fouling out your plugs. What excatly do the plugs look like?
