If it is an injector problem it would be one that is not opening. For mechanical problems the injector usually stick open; leaks causing a rich condition. Lean usually means the coil has gone open. Pull the connectors and, using a good ohmmeter, check the resistance between the two pins on the injector. You should get a value on the order of one or two ohms. One that is bad will usually show open but, in rare cases, shows a higher value than the rest. If one is a significant amount different, replace it.
