strip down as far as the valve and remove the carbon that may be causing it to stick, assuming that the electrical connections and sensor are ok
 
Looks like it has progressed or another separate fault !

Anyone recommend a cheap Merc code reader ?

I expect the throttle flap is knackered. I have done a few on 651 engines. Make sure you get both the upper and lower seal. They are fiddly to do too.
 
What knackers them ?

I haven't noticed any issues driving .
