Hi wc stoddard, Welcome to 2carpros and TY for the donation

Do you have a check engine light?

Lack of acceleration,chugging,hesitating,jerking,bogging,misfiring 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.

moisture in the gas tank. added bottle of moisture additive...took care of the problin

So much of fuel contamination

I'm glad the problem has been resolved and you coming back with the fix so that other people will learn from it-TY-Good Luck
