clunking wen on the gas
 

if i tap the gas i get bucked like as soon as i allow even fumes into the engine.....do you think its from a bent axel or something..maybe something with the rear?

it shouldn't be too violent, but i get mine from rear end play because of bad bushings. it never kicks hard but you can always feel the slop, even if you aren't hearing it.

worn out rear bushings is pretty common.

ok...how much do new ones cost?.........or wat do i do to fix the problem?

It could be several things. It could be bad bushings, but another possability would be that your PPF is cracked. That's what the clunking sound was in my car, you will also notice your shifter bounce up as soon as you gas it.

Pillow ball bushings should be around $50 bucks a piece depending where you buy them.
I got mines a MAZDATRIX.
