how would bad injectors make your car run in cotrast to just dirty injectors? whats the big difference?

 

Most of the time when an injector fails it hangs open or fully closed. If it is stuck open, then i might be hard to start after sitting, when started the cylinder will be dead because of the excessive amout of fuel in cyclinder. A fully closed injector will not allow fuel to flow threw the injector causing a dead cylinder. If you have a dirty injector most of the time you will feel it at idle. Your fuel is not being atomized corrrectly and you can feel a rough idle.
