Anyone else experiencing this?

I had something like this in a 95 Blazer I owned. Turned out to be the throttle postiion sensor.
I finally figure it out by downshifting od flat land so the throttle was in the same position as going up hill. At that throttle point it would stumble or lurch depending how you look at it.
