My Sonata only hits 3000 RPM's which is roughly 20-22MPH, not sure what the problem is, just happened this morning. I had to get a ride to work and would like to have some kind of idea as to what the problem may be so I know what I need to do when I get home.

Lack of acceleration,chugging,hesitating,bogging etc. could be caused by one of the following below.

Inspect and test all the following listed below:

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position 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.
