Hi TAMPICO,

Thank you for the donation.

Thee are various possibilities such as :

1. Throttle position sensor.
2. Air flow meter (AFM). Check if the sensor inside air flow is dirty. Use air flow spray cleaner to clean it. Be careful not to damage it with any physical contact.
3. Crank angle sensor.
4. Cylinder head temperature sensor.

Is the Check Engine Light showing?
Did you try to go into diagnostics.
