88 with 180 k on it 5 speed.

While driving in 4th gear at around 25 or 30 mph i have a bucking feeling. Additionally after i stop and try to restart it seems like it runs on 4 or 5 cylinders till i give it gas then it smooths out. I just replaced the fuel injectors, thats when i noticed the issue.

My suspicions are: fuel pump going bad or one or more injectors are not fully functioning.

Any suggestions? I thought of unplugging injectors to see if the problem gets worse, but after higher RPM it goes away, no issues at highway speeds.
