Electronic fuel injector test
What is the best way to verifiy if an electronic fuel injector is firing while still in the motor? Isolate it with a stethoscope and listen for ticking?

That works or just unplug the harness to the injector in question while the engine is running.
If the engine stumbles when you unplug the harness, that indicates the injector is firing

I had a bad injector on my 3.4 (from 3.2) and I personally found it very difficult to detect any difference when unplugging an injector.
The cylinder that is not getting fuel should be colder than the others. -Chris
