Throttle Pedal vibration

[mistahqEsi]

Hey all.
I've searched a couple of the forums here on this site and still am not sure if I have the answer so any further help is greatly appreciated.
The problem is that the throttle (gas / air / whatever) pedal starts to vibrate under my foot when I'm at around 80 mph (about 3500 or so RPMs). It's not bad, and goes away if I go faster or slow down. Actually, it even goes away if I push down on the pedal for about a second and then let off (getting the car back to same RPMs).
I've got a 97 Talon ESi with the stock 14" wheels / wheel covers.

Thanx in advance.

My pedal vibrates at 50 mph from my tires being chopped. (High and low spots on the tire.) Try a rotate and see if it goes away.

make sure your cables are routed properley. I don't see how that would affect it but it's where I would start.

get your wheels balanced.
