I have an integra 91, b16a, pw0 ecu, recently i have a problem only 3 cylinder was working, i chek everyting injectors are working, cables from ecu to the injector resistor are fine, cables to the ecu are fine, i found a solucion i found that the injector 4 i mean the cylinder four is not working because the ecu dont send the proper values because when i made a bridge betwen the injectors 3(ecu cable) to the injector 4 (ecu cable) the car works fine i'm asking what could be my problem? its right that i drive my car whith that bridge??. please i need some help. thanks
