my friends car is wired for obd1 (no resistor box) it was done by custom car care, and there is no resistor box...

he car is running like shit, dumping way way to much fuel, and the spark plugs are really black...and there is gas on top of the pistons.

so i think he is accidentlly running obd0 injectors...

and i have 2 sets of injectors, and im not sure how to tell them apart...

anymore info?
