Well I don't know if this is gonna help you but, standing on the drivers side, the injector connectors are color coded and they alternate from white to brown. It starts with white on the injector for cylinder 1, then brown for cylinder 2, white for cylinder 3, brown for cylinder 4, white for cylinder 5, brown for cylinder 6. And its really hard to get them mixed up, since the wiring is very short and I don't think you could connect cyl 2's connector to cyl 1's injector even if you wanted to. Maybe you should double check your ignition timing?

Hope this helps.
