Default Solved intermittant hesitation problem on 98 SLE

My Bonnie has this intermittant hesitation after warm up, taking off from a dead stop, until about 2200rpm. No engine codes.

After changing lotsa stuff, like TPS, oxy sensor, plugs, cables, etc over the years. I had heard that there are downloads for the ECM from Pontiac. So I took it to a dealer and they found 2 that addressed hesitation and stalling.

Fixed the problem.

I'm so happy. Best $170 I ever spent at a dealer.
