Hi,

I have now removed the crossover & black plastic cover. Used my stethoscope to listen to each of the injectors....the one closest to the firewall is quite noisy, the next one in is a bit noisy, then the rest seem "normal"...any idea on a diagnosis ? One more thing, it appears as though the black plastic cover is adding to the noise as I cannot hear the noise very well after removing it.

Any ideas ? Do I have a bad injector ? Where should I go from here ?

Thanks in advance !

Brian
