Hi there just wondering if i can get some help diagnosing this engine noise. It sounds like a rattling and rocking coming from the engine its way more apparent in the cabin than it is outside. The sound seems to be coming from the vtc actuator and ive done some research online about this issue on other acura models with the similar k24 engine the cold start sounds the same as the warm start and the sound only seems apparent around idle and 2k rpms anything after and redline sounds fine. I just want to get a second opinion before i order the vtc actuator
