Thom, If your fuel mixture is set properly and the vehicle is in good service ? Replace your catalytic converter, those magic pass smog juice only work marginally. Don't install hotter plugs , Mercedes has the compression,timing,temperature, and many other factors designed to work with the stock plug. Dyno testing is easier to pass only if the vehicle is dirty at idle. It is harder to pass because they measure NOX. S.
