i posted a thread about this issue that i've been having few months ago and i did not get ANY help at all. so imma try once more. this issue has gotten worse since then.

my problem is that my gas pedal vibrates very badly durin hard accelerations.

whenever i push the pedal halfway in or more, i feel this strong vibration in the pedal and when i release the gas pedal and hold it at 1/4 way in, the vibration seems to go away or be much weaker. it usually happens at 3-4k rpm. it has gotten worse and i dont know what is causing this.

100% stock car
automagic tranny
26k miles
91+ octane


any ideas? plz help. its annoying the heck outta me

 

What kind of intake you got? Did you tighten the throttle cable?

 

fully stock car. i haven't touched a thing. 1st owner kept it fully stock too.

 

try a rotation and balance, my car vibrated horribly especially when accelerating until i got my balance and rotation

 

the pedal vibrates, not the car

 

Do you lose power when its vibrating? It could be the engine misfiring. Tires out of balance can cause just the pedal to vibrate.

 

i dont lose power. also my car shakes badly at 70mph+. could it be tires? i got new tires tho. good year eagle 1 high performance summer tires. i think i need a balance

 

Balance Your Tires, Damn... I will bet you it's 100% that
