questions regarding a gas pedal vibration issue

[mslugx]

Hi everybody. I just noticed a problem with my 04 G35 sedan. The issue is when i am going on a constant speed, and i am lightly touching the gas, the pedal attends to vibrate or rattle, but that only happens to the pedal. If i step on the gas pedal deeper the vibration is gone, everything else is fine. I am just wondering what's wrong with this. could it be the spark plugs or other compartments? Thank you very much and have a nice day.

Its probably just the car begging to be driven with all 280 horsepower.
Its also a possibility that there are just chassis vibrations and things. I usually feel a little bit of vibrations/physical resonance but nothing to alarm me. Check to make sure the pedal is firmly bolted to the firewall. Its only held on by 2 nuts and studs.

Every so often I feel a vibration in the pedal of my 04 coupe.
Never heard a rattle tho.
If you push it to the firewall, it goes away!

These cars are a drive by wire design...so you're probably feeling normal vibrations.

Check your pedal with the car off. Does it have any play? There may be lose screw/bolt that holds it on.

Thanks for the reply everybody. If you guys say so, then I guess it's ok. I check the pedal and all the bots and screws are in place. Thanks for the help, please keep me updated if you guys find anything.
