Vibrating Gas Pedal/floor

[Metz3020827]

Anyone else experience this ever on their mustangs?

I realize it’s not a rolls Royce but damn is it annoying.

it happens as soon as the engine is turned on. If the car is moving at all it vibrates.

the pedal vibrates very slightly when idling. But I’m not sure how much is normal. You’d have to be focused on it at idle to know it.

I mean, at idle it shouldnt be drastically more than any other car(unless modified)

Even modified I don't feel anything in the pedal itself aside from residual vibration from the Exhaust ect. At least I don't feel anything concerning.

If it vibrates more than what you consider a healthy amount look into it.

Now if it shakes and vibrates like youre a Dual action Sander . That's might be an issue

Did you buy the car new or used?
Have you done, or are aware of, any mods? Especially suspension?
How many miles on the car and how do you drive it? I ask that wondering about the motor mounts.

I bought the car new and yes I’m lowered about an inch and a half on coilovers. 55k miles now.
I drive the car pretty hard. I was thinking it might have to be motor mounts but the usual symptoms besides a vibration aren’t there.

I know the mustang motor mounts are filled with oil and when bad will leak really bad. Not a single drop under the car. I’ve looked at my engine while revving and nothing. It moves a little to the right, but I’d assume that happens under power.

I honestly don’t think it’s engine mounts, how else would I know?

honestly it vibrates like from the exhaust but how much is normal? I have a h pipe and roush mufflers so I’m curious if it’s just my exhaust.

I thought it was my tires and I got that rebalanced yesterday.

I know this isn’t a Cadillac so I gotta give myself a break but dang I don’t know. It kind of makes my foot sleepy whilst driving.

my dad had a bad u joint on his drive shaft before, and that was alarming whilst driving. Nothing like that.

Adding the H pipe can certainly introduce some extra vibration. The more turbulence resonates through the system the more you'll feel.

It shouldn't be enough to put your foot to sleep though, and vibration would be in sync with the exhaust sound (mostly) if that's what your feeling

I don't want to give you a false sense of Doom, or relief. Since a vibration can be anything from normal exhaust rumble, to unbalanced wheels.

I will say if its something "major" usually it will present with other symptoms fairly quickly if not immediately.

Is the vibration getting worse over time?

The vibration seems to have stayed the same. I went and got my tires rebalanced on Tuesday thinking of being hopeful it was that. It’s been a few months (that I’ve thinking of)

Are you sure you are not feeling pulsating at all? When I had my Honda I did have a vibrating that was caused by my front axles and one rear barrings. How many mines on your car?

No pulsating.

You've owned the car since new. Has this vibration/buzzing been there since new? If not, when did you first notice it?
My only correlation is the handlebars on a 2 cycle bike and that's more engine frequency and mounting.
My feeling is your vibration is somehow related to your suspension. Maybe something is touching the body somewhere like an ac or cooler line maybe. I just don't really know what might be giving you a buzzing frequency. Figuring that out would go a long way in finding the issue.

Sorry I apologize, I meant I’ve bought it used. Bought it with 3 previous owners at 26k miles.
I’m starting to think it’s just the exhaust, catback h pipe. It does it at idle but I think it’s a combination, because during driving it’s rough bc of the coilovers and low pro tires. I’m switching suspension soon so hopefully it helps it a bit.

I think it’s just normal honestly I just overthink stuff.

Man, h-pipe with roush vibrate like hell, my own experience

The sound tube outlet is behind the gas pedal. Maybe play with that.

Maybe it’s just that. Doesn’t really bother me much anymore
