You need to figure out the air (vacuum) leak first. Is the oil filler cap tight? Has there been any recent work?

issue has been solved.

Had the same exact Issue on my 2011 tsx 2.4, took it too the dealer , they said it could be a number of things and gave a ridiculous figure , took it to my friend's mechanic, who suggested swapping out the VTC actuator as well . Did this yesterday, hopefully this has resolved the issue.

Happy to report the VTC actuator swapping has resolved the issue so far, No more issues with the car.
