i swapped a obd2b b20vtec into a 91 dx. Now it barely starts and does not hold idle. the **** misfires like a mother.

it has to be fuel or spark. i replaced the rotor, cap, wires, ignition coil and plugs. still no dice.


i noticed that on the injectors there is a (+) positive symbol on the side of it. The side with that symbol is where the ground wire goes (colored wires.blue,red,yellow,brown). is the power supposed to be running to those wires?

that might be one of the reasons why this thing doesnt really start.

 

blahhh

 

are you running a resistor box? If your using obd2 injectors they are saturated and you run no resistor box.
and your running obd0 still or did you convert? what dizzy are you using?
also, double check your dpfi-mpfi wiring.
