ENGINE

2007 Hyundai Sonata • 4 cylinder 2WD Automatic • 116,000 miles

Ok, so I have a 07 hyundai sonata, 2.4L 4Cyl. And for some reason when I go in the 80-120km speed range, the car seems to stutter a bit. Almost like its choking a little. The effects aren't major, but certainly noticeable. Any clues as to what it is?

Do you have a check engine light on?

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.
Throttle position sensor.
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.
Cap and rotor.

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