At the bottom you have ' 86 300E CONVERTED to 95 300E' what do you mean by this? If you have swapped engines, it may play a role in diagnosis
Symptoms: Exessive fuel consumption, Exhaust smells of gasoline, Black soot from tailpipe, Black smoke under full throttle, and a strange 1 sec. 'surge' when i touch the gas pedal.
This could be many things, fuel pressure regulator, bad plugs, bad wires,burned valves,bad valve guides etc
Warm engine - unplugged O2 sensor - measured 0,77V at idle and 0,81V at 2000 rpm from the sensor. (should be in range right?)
No, O2 Volts > .45 is rich
More info on what the 'conversion' means will help
