Yes, a clogged catalytic converter can lead to fouled spark plugs. When the converter is obstructed, it can cause increased exhaust backpressure, leading to incomplete combustion and unburned fuel entering the exhaust system. This excess fuel can then accumulate on the spark plugs, resulting in fouling, which can affect engine performance and efficiency.

A clogged catalytic converter? Or some other exhaust pipe obstruction. Try removing an O2 sensor on the exhaust and see if it accelerates then, if it does, your catalytic converter could very well be clogged. Also, if your EGR valve isn't working properly, it will cause your engine to stall out. Hope this helps.
