I was driving about 50-60mph and each time i let off the gas the car started to buck back and forth until it got around 40 or i went back on the gas. Does not happen to the car at lower speeds, never tried to go faster to see if it does up there. Just got me a lil unnerved lol.

Is it to do w/ the Rear-end? Transmission? i got no clue lol, is it possibly normal? haha idk >_<

Does it do anything else or make any other sounds? Does the engine sound the same as it used to? Or did it change slightly? Check engine light come on?

sounds are the same, theres a constant faint ticking but i was told it was just the lifters. Check Engine light is always on because the P.O hollowed out the cat converter.

Have you done or know when the last tuneup was done on the car? Plugs/wires/fuel filter/cap/rotor/pcv/etc.

after a quick look all that i could tell was fine, but the plugs were pretty fouled gotta replace them. Don't think the plugs would cause this :/ ?

Does this happen only after u reach overdrive? Could be ur TCC ..but then again I'm an idiot..what do I know....
Could also be an intake gasket..cause once u let off the gas the pistons are drawing more air into the chambers which causes more vacuum..and if u have a bad intake gasket it would make it more prevailant..remember 2 things though...1) it can also be other things 2) I'm still an idiot

as for when i reach overdrive, dno i don't shift myself i jus keep it in drive. and If it were the intake gasket wouldn't it happen everytime i let off the gas? this seems to only happen around 50-60mph and randomly when it does infact happen.

I know nothing about the mechanics.
