Unplug your MAF and drive the car and see if this has any effect. I had some power issues with my '99, one of which was where it would hit the 4-5k rpm range and would just not pull through it, it was most noticeable in 3-4th gear, the power just went flat.
I tried a number of things to fix it, cleaning the throttle body and tps valve to name a few. It turned out to be my MAF, which I did not even initially consider since I wasn't getting a CEL.
Once I changed it, all my power issues went away and the car ran fine again. When I think about it, I wish I would have unplugged my MAF first as it was definitely the easier thing to do compared to everything else I tried.
Good luck with finding a fix.
