[W126 Coupe] Rough idle

[Mister McGoo]

Marcus;

I only have one experiemce with "aftermarket" ignition components.  A few 
years ago I used Neihoff because they were significantly cheaper.  The 
distributer cap self-destructed in the first 1000 Km, and I threw the whole 
lot in the garbage.

Since then I have stuck to Bosch cap & rotor and Bosch or Beru ignition 
wires.  I prefer the Beru for the quality of construction... they appear to 
be better fitted and sealled.  Having said that, I can't say I have ever had 
a problem with Bosch.
