Hey, thanks for the help on other issues. I've got another one that I need help with. There is a VERY LOUD pulsating sound comming from the fuel rail and injectors. You can even hear it when your sitting in the cabin. It got louder after the head was rebuilt and now the engine has a noticable idle fluctuaion. Even does it up to about 1500 RPM. You can feel the pulsating when you touch the fuel rail. Could this be a bad pressure regulator or injector?????? I just installed a new Bosche Main fuel pump and filter because I wasn't sure how old they were. Thanks for any help. TURBOS RULE!!!!!! :blush:
