What would be the effect of a plugged restricted fuel injector?
When the fuel injector flow becomes restricted or blocked the engine controller will attempt to increase the fuel flow by opening the injector for a longer period of time, increasing the injector pulse width. The slowest unmetered fuel leak can often transmit more fuel than necessary at idle, causing a rough idle.
What will the effect be if you have a fuel injector valve that is dripping after the injection is finished?
If fuel dribble occurs after fuel injection, the fuel in the cylinder will not burn completely. This will result in the emission of black or white smoke being exhausted.
What causes an injector to fail?
So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.
Why does my DD15 injector keep acting up?

He had a hard time getting it to fire off, and when it did, it ran away.
Can a bad fuel injector cause a leak?
A car injector delivers less quantity of fuel than required, or in some cases more; it reduces the engine’s efficiency, and can even prompt the CEL to be on. This kind of situation can be confirmed with the use of an OBD2 scanner. Fuel leak – Old age or damage can cause your fuel injector to crack or break, which may make it start leaking gasoline.
What happens when a fuel injector stops the engine?
What this means is that while in motion, your engine is likely to hiccup, or vibrate in a bid to conclude each cycle without the needed fuel. Engine misfires – When a clogged injector stops your engine from getting enough fuel, it is sure to misfire while in motion.
