Gas Pedal Flutter or Vibration - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hi I've been having odd vibes in my L99 SS. Sometimes while accelerating I will feel a vibe in the steering wheel. It is usually repeatable around 2000 RPM. Recently I am feeling it in the gas pedal. Same thing around 2000 RPM I will feel a BZZZZ through my shoe and then its gone.... I know its not tires as it can happen in different gears and speeds and only with throttle applied. Dealer agrees no issues with my tires or wheels.

I have had the car to the dealer several times about this. Drove it twice with the shop foreman there. Last time he said he felt it but assured me its normal for a large V8 and a sports car. He said it is the exhaust that runs under that area. He said its the stuff in the exhaust for the AFM baffles etc. For the record I have AFM disabled with the Range except when I take it to them....

I know the car is drive by wire so the throttle isn't connected to anything really. This is really annoying me and I would like to figure something out.

Does anyone have any idea what could be creating this? I believe it is some sort of harmonic.

Thx,

Hmm no insights so far? I was driving it last night and when the AC is on I don't feel it which is very strange. Turn AC off and then it does it again. Could this be a pulley or something causing the vibe?

I'm going to see if there is another local dealer who will check the car out....

Update of sorts. Took it to a second GM dealer they also said car was fine but could feel it. He said he has tried to fix it on the 2014 up trucks but only made it worse.... He says it is drone from the exhaust causing it.

What I realized was I have had my foot placed very high on the accel pedal which allows me to feel it through the firewall. When I place my foot where it actually belongs there is no vibe so adjusting my foot position has solved the vibration for me thank God!!!
