I don't Know if an 1987 Camaro has a (T.P.S.)Throttle Position Sensor, but if it does it may need to be replaced. My '92 Integra did that and I needed to replace to T.P.S.

On 2.8L, 5.0L and 5.7L fuel injected engines, with the engine RUNNING and all accessories off, use a jumper wire to connect diagnostic terminal B and ground terminal A of the 12-terminal Assembly Line Diagnostic Link (ALDL) usually located under the left side of the instrument panel. DO NOT disconnect the 4-wire EST connector at the distributor. Aim the timing light at the timing mark; the line on the balancer or pulley will line up with the timing mark. Increase engine speed and check for timing advance. If the timing still advances with engine speed, perform next Step . If timing does not advance with engine speed, proceed to last Step.
Remove the jumper wire from the ALDL, and shut off the ignition. Disconnect the Set Timing connector, usually located under the plastic cover above the heater unit, in the engine compartment. (The wire in this connector is normally Tan/Black.)
With the engine running and all accessories off, aim the light at the timing mark. The line on the balancer or pulley will line up with the timing mark. If a change in timing is necessary, loosen the hold-down clamp bolt at the base of the distributor. While observing the timing mark, rotate the distributor slightly until the line indicates the correct timing. Use the timing specification on the emission control label in the engine compartment. If this label is missing or damaged, refer to the Tune-Up Specifications chart in this Section.
Mass Air Flow (MAF) Sensor
The Mass Air Flow (MAF) sensor, found on some fuel injected engines, measures the amount of air passing through it. The ECM uses this information to determine the operating condition of the engine, to control fuel delivery. A large quantity of air indicates acceleration, while a small quantity indicates deceleration or idle.
clean it with eletrical cleaners

sounds like it's bogging down under a load, assuming that it doesn't need a tune -up or the fuel filter replaced i would advance the timming slightly and replace the vacume advance on the distributor and the line that runs to it

When you mash the pedal and dump more gas in than the engine can burn, it hesitates. Figure out how to burn more, you wont hesitate as much. Plugs, wires, ignition control parts are a start.

Gas filter dirty, air filter clogged up, timing not right, spark plugs no good, transmission low fluid or clutch worn out.... so many thing make it bad... take it to the shop for diagnosis...

timing, if it has a carb, it could be the accelerator pump on the carb. Good luck

Check your spark plugs.
