S600 W220 misfire when NOT driving

[J19 HWS]

If I try revving the engine whilst standing still it will not rev above 2300 -2500 rpm without trying to cut out, when I'm driving there's not a single problem with it, idling is smooth and when on the road I can floor it and doesn't miss a beat no loss of power, any ideas anyone?

Aren't some MB designed to to this when stationary seem to remember a thread on this very subject with rev limiters coming in earlier than expected when stationary

Entirely normal to protect the gearbox/converter I believe

I was told on my e55amg this is to protect engine when NOT under load

As above, also why would you want to rev it any more?

My Sprinter wont rev above 3000 rpm in neutral, not sure about my CLK but I do like to let diesels idle for a minute from cold. They are big old highly stressed lumps and from cold starts need a minute or two before being revved.

The only reason was when hooked up to my star reader a certain test asks to hold revs at 3000 rpm for 1min, this is when I found you can't do it
