i was driving down the street and my car startd running on 3 cylinders and the dash lights/headlights were getting dimmer and the speedo was going crazy so i pulld over and unplugged each injector clip but on cylinder 1, the idle didnt drop when i unplugged it...............so which wire needs the 10w 10 ohm resistor out of yellow/black or yellow/green and if that doesnt fix the problem could i have blew the injector itself? or why is my car only running on 3 cylinders thanks a lot

It should be the yellow/black wire. If you look at the others, they all will have one common colored wire, and the other 4 will be a combo of blue, red, brown, etc. All the grounds should have their own resistor, but you can really put it on any of the two wires per injector.

And just to ask - are you running an ecu chipped for dsm 450cc injectors but not running any resistor box/resistors for the DSM 450cc injectors? It doesn't take long for the increased amperage to fry your injector circuits inside your ecu when you run DSM's but no resistor.

well if i switched ecus then wat could be the problem? becuase i just tried a brand new ecu and same problem...........
