Car has 20K miles. Car bogs down at 40mph. It sounds like it is "blowing bubbles" under water. If I give it heavy gas the car powers through, and noise disappears. Used super for 2 tanks of gas and tried a fuel cleaner. The mpg has dropped from 30-31 to 24-26. Any suggestions?

Lack of acceleration, chugging, hesitating********, 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.

Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.

Note:If it doesn't apply disregard it and keep testing.
