Fuel psi drop test
Here is the procedure outlined by Gerry at CSC for detecting a leaking injector:
Connect a fuel psi meter to the fuel line
Start the engine
Fuel psi should increase and maintain psi as engine is running
Turn engine off
Fuel psi should hold 80% of its value for at least 20 minutes
Checking the fuel psi drop is the best way to determine if you have a leaking injector.
I will relay my findings when I do my test.
