i just got an Rx7 last week it was working fine. the guy who sold it to me is Justin Palawk. he got first place in one of the D1's. not sure.. but you can check out his website JTPDRIFT.com great guy. but the day after i had it the check engine light came on. and what happens is that if i press the petal to the floor the car starts bouncing, and it feels like the car is trying to breath... i don't know what the problem is.... can anyone help me.. ??? im a noob to rotary's and im trying to learn by having this car.

 

I got the same problem as you man. Im also looking for an explanation.
