I have Slow accelleration until 1800-2000 RPM then a miss until over 2000. Everytime this occurs. I had the injectors cleaned, using 93 octane, had coil check out and apears to be ok. I am running fuel cleaner through the gas tank with no improvment.

Hi richard.E. Merrill, Welcome to 2carpros and TY for the donation

Lack of acceleration, chugging, hesitating, bogging etc. Could be caused by one of the following below: Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note: If it doesn't apply disregard it.
