I found a small oil leak at the valve cover. I sent my X to the garage to change the valve cover gasket and spark plugs at the same time. The engine is a bit hesitant when accelerating. It seems that the car is not responding as it was before. What could it be?

Thanks in advance for your help.

assuming there is no check engine light from a missed electrical connect during install, you must perform:

Throttle relearn procedure;
Idle relearn procedure.

This should fix it since they most likely were moving the intake and throttle body to complete the install.
See Ry the car guy for procedure on Youtube.

Report back if this fixes it.

Hi Boyer, that might be the case, indeed. I found the videos and will follow the steps myself to see if it re-learns my driving style. Thank you for pointing me in this direction.
