I replaced my intake manifold. When I started the car it makes a loud rapping noise (sounds like loose metal in a dryer) in the engine and idles real rough. The sound is so loud that I don't want to run the engine. I have every nut and bolt, but it sound like something fell in the intake port. Could it be something else? If something fell in the engine how do I tell where it is? Do I have to remove the head?
HELP!
Thanks
