The clogged catalytic converter could cause the car jerks when accelerating. If the catalytic converter is dirty and not working efficiently, try to use the catalytic converter cleaners. Otherwise, you need to change your catalytic converter or have your car serviced. 10. Faulty Mass Airflow Sensor.
The traction control light (also known as the TCS light) indicates that there is an issue with the car’s traction control system (TCS). The TCS applies brake force to certain wheels to keep them from spinning too fast or losing grip on the road surface. It also monitors wheel speed sensors to ensure that all four tires are getting equal
Engine hesitation is something that you may have experienced but weren't sure what it was. We use the term engine hesitation to describe the phenomenon that happens when you put your foot on the gas pedal to accelerate and then experienced what seems like some power loss from the engine for just a brief moment.
When trying to answer the question of “why the car doesn’t accelerate when I push the gas,” the most common reason might be the mass airflow sensor is clogged or damaged. The mass airflow sensor, also known as the MAF sensor, is connected to the air cleaner. Since the airflow sensor works to measure the air that is flowing into the engine

No check engine light or any other issues..
TiffanyTwisted. This is an old post but never got a response. Diesel engines make their maximum power at low RPM, and if you accelerate hard causing the vehicle to downshift into a lower gear, thus raising the RPMs, it will noticeably have less power. Keep the RPMs low and in a higher gear to have better power when climbing steeper grades.
Explanation #1: A Problem in the Fuel System. One of the most common causes of a sputtering engine is an issue with the vehicle’s fuel system—the filter, pump, and injectors. These three critical components work together to ensure fuel flows smoothly from the fuel tank to your engine’s fuel injectors, and then pumps into the engine evenly.
