The first place I'd look would be at the fuel system. If the system pressures haven't been checked in a while, I'd do that first, and then set the basic mixture (you need an exhaust gas analyzer to do this right). Also, fuel injection needs CLEAN fuel--has the fuel filter been changed recently? Hope this helps, Bob at Pelican Parts Wayne at Pelican Parts wrote: > Maybe you're running rich?
