idle fluctuations, power fluctuations

My car is a '78 99, with an '87 motor in it - my question involves a possible problem with the LH system:
When the engine has fully warmed up, the idle usually rises and falls rhythmically, about every 3 or 4 seconds - sometimes the oscillation is a little longer. It floats up by 2-300 rpm, and then floats back down.
Also, when driving (again fully warmed up), I can feel surges and ebbs in the power that seem to have the same timing to them.
I am wondering if the AMM resistence could be off enough to cause the LH system to try to compensate in some way, or if the coolant temp sensor is a more likely culprit? Any other ideas on where to look?
thanks,
Rowan
