mates,

if you've gotta bad injector or plug, how do you diagnose which one?

cheers,

sv-

Bad injector will make funny noises after its warmed up all the way. Loosen the line from the IP to the injector and see if the noise goes away. A bad plug will generally cause a miss on startup. That's as far as I'm going because ALL OF THIS CAN BE FOUND BY USING THE SEARCH FUNCTION!!!

Injector testing:
#1. Engine running at idle.
#2. Loosen only one injector line at the injector (a 1/4 turn should be enough).
#3. listen for changes.
#4. Tighten injector line.
#5. Repeat for each injector.
