Car keeps overfueling on cylinder 3 causing the spark plug to become saturated and not work properly this happens every 50 miles or so . Which means i haft to keep taking the spark plug out and cleaning it what could be causing this?

When you say fifty miles or so, is this on a long journey, or over quite a few days running? Do you feel the difference immediately, or is it a gradual loss of power. It could be that the dis or dissy is breaking down when it is really hot, or the lead doing the similar, or the plug. cannot be an injector problem, as this would show right away.

Unless the plug is being fouled up by oil, it just has to be the plug. When was the last time it had a service with new plugs, oil, air and petrol filters?
A breakdown of a lead, dissy or dis pack through heat does not accumulate over a few days, therefore you can discount this theory. Petrol is obviously being delivered to the cylinder, so it has to be the plug, or a sticky valve, which is occuring only intermittently.
Try swapping the plug with another see what happens?
