Default 560 SL running rough
Just bought a 1987 560SL from ebay and it runs rough on idle. It sounds like it has a racing cam. It idles rough. Took compression and got 150psi to 135 psi all around. Plugs were all clean, replaced plug wires, plugs cap rotor and fuel filters....still no improvement. Any tips?
