Either transmission is slipping or engine has an intermittent misfire issue. Also, slight chance your a/c compressor could be cycling quickly if the charge is low


...also, could be something fuel related such as a bad oxygen sensor, fuel filter, or MAP sensor. Is your check engine light on?

I'd suggest a vacuum advance mechanism on your distributor, but you've neither with this one~


Could it be the transmission torque converter lock cycling?
