Your coils may not be firing properly. Its common. Take all the coil packs off. Next take the boots off and the springs out of the contact points. Next take a cheap $10 dremel from harbor freight and dremel the contact point on the inside of the back and bring it to a nice shine. Replace or use electronics cleaner on the springs. Reassemble, and use electrical take on the boots; wrap them up!!
Now hook everything back up. Start the car, listen for misfire. Unplug one coil pack at a time, listen to see if condition worsens or stays the same. If the condition stays the same, you may need to replace that pack. To confirm switch one pack that made the condition worsen when unplugged with that pack. Also, take your igniter to have it tested. I would recommend a buick skylark coilpack conversion and a z32 igniter swap. Fixed all of my hesitation issues when I first installed my rb20 and its really simple to do.
