2013 G37 Engine Hesitation issue

Postby AliefZee » Fri Mar 03, 2023 3:17 pm

Had a mechanic recently replace the head gasket on this engine due to a leak. Few weeks prior to that spark plugs and fuel injectors were replaced. Now it is severely hesitating when i try to accelerate almost like a lack of air or fuel. If i slowly press on the gas to build up speed there is no issue. Any ideas on what I'm dealing with? I plan to take it back to the mechanic so he can troubleshoot but i have to manage it for a few weeks due to me needing the car for work. Don't see a video attachment option so i posted the video showing the hesitation as i try to speed up below
