Hello everyone, i just found this forum and hopefully I can get some help from here. Earlier this month I got me a 08 G37s with the 6speed transmission, I love the car, the engine sounds healthy, transmission doesn’t have any grinding or any weird noise.



Last Saturday I went to the shop to do a complete maintenance, they changed oil filter, engine oil, transmission oil and diff oil.



Car runs perfectly, but yesterday coming from work, when I parked the car, I revved it and heard a click noise it sounds every time I hardly press the gas pedal (flooring it). When I rev it like with a 50/60% of gas no click can be heard.

• All fluids are good
• It seems it has new belts on it
• New spark plugs were also installed by the previous owner
• New clutch was also installed by previous owner

I believe it is coming from an upper area in the passenger side, I am not sure what it can be.



Please help, I don’t really want it to be a serious thing as i already had bad experiences with my old car (04 350Z).



PLease see the video (3 videos In 1): https://youtube.com/shorts/K8tQIwnYIxg?feature=share



Thanks.



Will.

 

Probably I am having the same issue, when I floor the pedal in Neutral, Park, or Drive. If the engine is on idle rpms, if i hardly floor the pedal, it sounds like a knock. I couldnt figure out the cause.

 

Well, I later found out my car was tuned a few years ago so it is probably something related to that. Car is running perfectly after 3500+ miles since July last year 👌🏻

here is a video I found that shows my exact same noise.

That is the exact same sound I am having. Have you reverted back to stock tune to solve it or retuned it again?
