Willie - Have a look at the main ground stud for the ignition coil and other related electrics. The stud can be found by removing the vertical carpeted panel at the rear of the parcel shelf. The stud will be facing you, on the "passenger" end of the shelf, about 8 inches above the shelf with two large black wires typically attached. I would recommend taking the connection loose, cleaning everything, and then reinstalling with dielectric grease. This ground is involved in the coil, as well as the signaling to the tach. As an aside, if you look to the left, around the corner of the underbody from this ground stud, you'll see another large stud sticking out of the fiberglass with a bunch of large brown wires attached. This is one of the main +12 volt power buses, and is also the jumper post in the engine compartment.

The strange thing is I don't feel any sort of rpm change in the car. It does not speed up or buck, it acts as if nothing is happening with the rpms.
