I had my buddy clean my injectors at the shop he works at. They use an ultrasonic cleaning machine and then they flow bench test them afterwards. We didn't flow them before the cleaning, but he did after the cleaning and the flow pattern was good. I had a low rpm/ light load surging-bucking problem. The car especially when cold, would jerk and buck when trying to drive under 2800rpms and light load. For example, before the cleaning, driving in 5th gear at about 30mph was painful. I'd have to keep it in 4th to keep the rpms past the "surge point". Well, I threw the injector back in, fired it up, and drove it around my neighborhood with no symptoms at all! So, if anyone has the same problem, try cleaning the injectors!

I'm glad you figured it out but you aren't supposed to be going that slow in 5th anyway.
5th is for 50mph and up.

I know, but it didn't matter what gear I was in. If I was in 3rd gear and 1500-2500 rpms it would buck and jerk....
