I've got the exact same problem with my 2000 cougar v6 with about 90k miles. While driving, the RPM's bounce around, the throttle pushes down, and the car 'surges' forward. I was told this was an O2 sensor/Cat converter problem, so I removed the cat and straight piped it, it didn't fix the problem. Anyone have any ideas?
