Weird Engine issue. With VIDEO! (You love video!)
So my 2000 s10 Blazer has been doing this for a few months now. Everything else seems normal.
While accelerating, the RPMs seem to be fluctuating like crazy...like smoker trying to run a marathon. See the video for better explanation:

Not sure what is causing this...

Since you say that "Everything else seems normal", I am going to say that the tach movement is not engine related and is most likely an electrical issue or the tach itself. That much rpm fluctuation would be felt, especially while accelerating.

My apologies for not being more clear--it's definitely an RPM fluctuation, because I can feel it, too. Outside of THAT, everything seems normal.
My thought was to take it to a tranny specialist and get it checked out.

Ok that helps. A bad torque converter will act in just this way. Apply just enough brake pedal pressure to apply the brake lights. That should disengage the tcc. When doing this and if the fluctuation does not go away, then it is not tcc related. If it does stop and comes back with your foot off the pedal, then the tcc is the issue.
