My 2005 G35x seems to runs beautifully. Except when I have the windows down and am next to a parked car or something that noise can bounce off from.

If I suddenly press the throttle hard not necessarily WOT but a good press Ill hear a knocking or clickity noise from what seems like the engine or front axle.

This noise only sounds for a second or 2


any ideas? could it be the regular Gas I put in it?

Thanks

 

You need to verfiy and make sure exactly where it is coming from. If it is a clicking or knocking noise from motor, sometimes it could be due to low oil... I say that because I had a motor that was consuming a lot of oil and at one point it was really low so once I put in more oil, it stopped the clicking sound.... if from suspension, number of things. VERIFY THE LOCATION.

 

It sounds like it could be pinging from lower octane fuel. How long has it been doing this?

 

use 91 octane or better, and check your oil level.

 

it's engine pinging (knock) caused by the regular gas. use premium and you should be fine.
