No throttle response from 92 model S420

Have a 92 model S420, (140 chassis) with an intermittant problem where I have no throttle response. There is no way of reproducing the fault as each time the senario differs. I can tell you that there is an extreme smell of sulphur (rotten eggs) when the fault is evident but the fault will clear itself within a minute or two. I know that the throttle is fly by wire and wondered if any body has struck anything similar?

Thanks, Gary.

RE: No throttle response from 92 model S420

the sulfer/rotten eggs sounds like the catalist if fitted? is about to fail, the lack of throttle response is probably the exaust getting blocked and killing the engine
