And you feel a small vibration or shudder every couple seconds in the seat.

The spark plugs and oil was just professionally replaced and it was doing this before but I was praying that new plugs and oil would fix it.

Anyone?

Check the runout on each end and middle of the drive shaft.
Maximum runout at ends is .005" and .010" at the middle for a quality drive shaft.
Excessive runout can induce vibration energy into adjoining structures.
The driveshaft can be dynamically balanced even with excessive runout.
My RCSB has a single section aluminum driveshaft. All other configurations have two section steel material driveshafts. Much easier to straighten a steel drive shaft compared to an aluminum material drive shaft.
