Your 92 300E doesnt have a MAF sensor.Some of those cars have 2 fuel pumps.Make sure they are both working.A clogged cat could definately cause the problem you are having.Install a pressure gauge in the 02 sensor port in the exaust.It should'nt go above 2 psi when the throttle is stomped.If it does,it needs to be replaced.Another possible problem is a varnished fuel distributor.If its not bad,some good fuel system cleaner could help.
