How do I test the flow of an fuel injector off car? I am getting a P0300 Random Misfire, with high HC and high NOx. Replaced all ignition components and tested coil spark. MAF tests per spec, as well as TPS. I plan to hold attached fuel rail with injectors attached and fuel pump running over a small bucket and observing the spray pattern of each injector as I energize each with 12 volts. Does it matter which way the 12 volt wires are connected? I am looking for a conical spray pattern, right?
