I have a situation where my 1991 mercedes 500sl has a misfire from start up then goes to high idle when warm. After testing all known obvious causes (plugs,wies,caps,ezl,coils,fuel distributor) most of which defied a logical reason to be tested as the misfire is all on bank 2 which is getting good spark and fuel. I pulled each wire one at a time with no change in idle. Compression 128 across the board. Where would you look to next?

@@deborahanddanmorgan6145 The timing. Is it set as it is initially supposed to be? Is the groove aligned with TDC mark, is the timing chain aligned with the groove to the opposite side? And is the rotor facing towards the first cylinder?
