Engine/Transmission (1994 - 1998) Interesting vibration

[TGaines]

I have noticed an interesting vibration lately while idling in my truck. It appears that the vibrations increase and then decrease in a cyclic fashion. It's not really bad, but noticeable. I was wondering if that was a sign of something major, or just the way these engines run. Hope it's nothing serious.

I'm questioning if your idle may be low and your a/c compressor is turning on and off in normal operation. With a low idle you may feel the compressor action.
