Well, it seems you have a problem with either TPS (Throttle Position Sensor) or you have a problem with spark plug(s). Check out if you have the correct spark plugs and are properly gauged. For 93, the spark plugs should RC12LYC gauged at.035. Also, you can check if you need to replace spark plugs cables. Remove the cables and check them one by one. With each cable, check it ´s respective spark plug to see if it has scratch like marks on the sides all round. If so, replace the cables.
Other problem could be the timing. Try rev the engine at P to 3000 rpm. Slowly then fast. If there is something like hesitation, then it could be timing problem.
