Well the car is 90 integra with a gsr, the car was misfiring, i found it was cylinder 4 causing the miss, i did a compression test, i pulled up the all data, to find the stock spec resistance for the injectors, i check the resistance on the injector, and checked the injector plug with a noid light, i also did a running compression test

compression test good, and the injector and plug are good, so im thinking wtf is causing this?

so i check all the other cylinders,i get to the number 3 cylinder, and the resistance on it is 17 ohms, so im like WTF, why is the number 3 injector deffiently bad, but no missfire on that cylinder, and number 4 injector is fine, and has the missfire?


so i think for a second, i pull up all data on my computer and look at the wiring diagrams, i get to the A-3 Engine cranks but wont start, which has the injector driver circuit on it, and it clicked, cylinders 1-2 fire in pairs as well as 3-4


so i figured, the number 4 injector was using more current than its suppose to, robbing power from number 3 of enough power to keep it open


anyway just figure id post this, just incase this ever happens to anyone else
