[V8] bunch of codes

[Dave Saad]

I have done this before, but the procedure is actually quite dangerous.
You need a spare fuel pump or some way to pressurize the injector, and all the assorted tubing/wiring/power supply, etc to hookup an injector on a "test bench" which obviously means you removed the injector from the car.

For the "test fluid" I used a bottle of Techron so I gave the injectors a good cleaning at the same time.  In fact, that was my primary goal.

This is essentially what the pros do, except that they have safe working conditions and proper equipment and training.
I usually don't let little things like that get in my way. :-)
You need to find an explosion proof way to switch the injector on and off.  Sparks - even tiny ones are a bad bad thing.

I worked outside, with the electrical stuff far away, a fire extinguisher handy, and the garden hose on and ready for action.

Make sure your personal and property insurance is paid up too...
