I figured that that's why I asked the question's I did it's really common for 2000-2002 saturn S model single overhead cam intake gasket's to leak at the number 1 intake port. Let me know if you need instructions on how to replace the gasket.

I posted a diagram of the wire's on the coil's and the cylinder's number's that should help you sort out if the wire's are correct. As far as the gasket goes I would go with the felpro one.I think when the engine's were built at the factory someone was wrinkling up the gasket's upon assembly because everyone I have seen that was leaking you could see it wrinkled up before taking it apart to replace the gasket.
