Would I be better off replacing all 6 with the new model number injector or trying to source just one of the old ones and doing that? I replaced the cylinder 3 injector probably 2,000 miles ago so maybe better to just do this one instead of wasting the cylinder 3?
If it were my car, I'd probably just replace all the injectors with the latest version and be done with it. That and the valve cleaning should make a huge difference in how the engine runs and performs.
