I don't think it is a stopped up cat, the exhaust pipe is blowing like a mofo at idle. It's getting dark here, and I just revved the engine like crazy to see if I could get an arc out of the wires and got nothing.
I also forgot to mention that this happens while under load and just sitting in neutral. It's like somebody shut off the gas at 5000 rpms under wide open throttle in first and second gear.
