Engine hesitation?

Hello,

The throttle body / throttle actuator can be easily removed and serviced.
To remove the throttle actuator, you will first have to remove the air intake tubing, disconnecting any sensor on the tubing like the mass air flow sensor.

Here are couple of helpful guides on how to service the throttle actuator:

Please let me know of any questions.
Thank you.
