this is givin me a headache!!

my car has a vibration that feels like a tire with only 2 lugnuts on it(u know how it would vibrate like hell wobblin back and forth). thats the best way i can describe it, but i know its not my tires, it only does it when im accelerating, the more gas i give it, the harder it vibrates. i jus replaced the TPS, and i know it didnt do it bfor i changed that, but its set alright (at .968), so i dont know what the hell could be causing this!!! well i have a couple of ideas, but i want to know what u think it could be.

hey balancer, good idea, never crossed my mind, but if it was the balancer, wouldnt it have some kind of vibration even at idle?


Good question, and though I don't think it's your balancer, it's still a possibilty. If it is your balancer than the vibration would be RPM dependant and wouldn't just act up when on the accelerator. That said, think back to the vibration... does it only happen when you're putting power to the ground or does it vibrate when the RPMs are up as well?
