Can I disable the EGR on my 450SL?
I have been fighting a rough idle problem for a long time. I've tried everything plugs, wires. Dist.cap&rotor, set timing, add. air valve, fuel injector seals, tracing vaccum lines from diagram, adjusting fuel mix w/ gas analyzer. I still have rough idle IN D idles ok in P. Can I disable my EGR to see if thats the probleM?
