        well, i ran the self test and got codes 95 and 31. 95 is from not hooking up the vss wire to my new ecu which from what i understand is fine. but the 31 was for my EGR so i swapped it our for a spare i had and the motor idles and runs allot smoother and no engine light flashing for today. Substancially more power also.

        #3 got a new plug and wire swap and its still chalky black and the other plugs are light tan so looks like its time to throw in a new injector.

          You'll get a little off-idle hesitation with no vss input, but you should actually have vss wiring to the ECM connector on a 91. Possible the stock vss wire lands on a different pin though.

            Wire for the VSS is in the same spot between the Mass Air and speed density models. My check engine light flashes at me too. It flashes that code too... Hmm, might have to look into that for myself.
