2000 Olds Bravada Surging Problem

I just recently purchased a 2000 Olds Bravada. Today was my first day to truly drive it (besides the test drive). Overall it runs pretty good for an eight year old vehicle with 150,000 miles but there is one disconcerting thing that I noticed. When I was going up a rater steep hill (on-road, that is) I noticed that the vehicle surges or pulses. It seems to surge ahead a little bit then back off. It didn't do this on the test drive (of course), otherwise i wouldn't have bought it. It doesn't really feel like the transmission but I'm no auto mechanic. Can anyone give me some insight/advice?

Welcome to AF.
Any check engine lights on or blinking?
How is the secondary ign system?
Plugs and wires?
How is fuel filter and fuel filter?
If you just bought it.
The people you bought it from may help you out on it.
Contact them and see.
Good luck

I have no warning lights and it starts just fine. I did think about checking the plugs... I guess I better do that. I hope its not the fuel pump. i let you know when I find out.

Check your transmission fluid. I have a 99 blazer and it surges while driving when the fluid is low.

I did notice it was a little low but it still was over the line... could that still have something to do with it?
