Post 84 3.2L fluctuating rpms

The rpms on my 84 Carrera fluctuates about +/- (50-100) rpm at a constant interval, like a sine wave. It does this regardless of whether it is idle, driving at constant speed or accelerating (warm or cold). It's a nuisance thats been like this for about 3 years or more so it's been a low priority. I just had a 60K service with no luck. Any ideas on where to start looking?

Have you tried disconnecting the O2 sensor?
