Weird hesitation (not 3800rpm)

Here are my symptoms so far.

-Only happens when hitting bumps
-Only on accel
-No codes
-Not bad enough to jerk the car only to make an audible change from the exhaust. It pretty much sounds like you have your foot on and off the gas really fast multiple times when you hit a bump.
-Happens throughout the RPMs

Theres no parts places open today that have what I need, but I'm going to replace the fuel pump sock filter for sure..anyone else have any ideas? Fuel filter? Pump? Grounds?

I have no idea where to look on this one. If it helps the car is a 91 NA with 42,000 miles.
