ok dont know what was going on with the car for them couple of days, but whatever it was its fixed itself.

but now im haveing an issue with the car not only running rich as hell i mean it burns your eyes rich, getting about 8-11 mpg now. there is i guess a cloud of smoke that comes out of the back of the car when i push the motor hard <its not blue smoke or white, just dark> i dont know this now for a fack because i never look behind me when i go.

but other than that ill be going along, fast, and then the BOV will purge and then the rpms will just drop down under 500rpms either it will sit low for about 2 seconds then recover itself or it will go down to about 200rpms and then usally it will just shut the motor off.

well thinking it might have been the new hard pipes for the IC i sprayed starter fluid all over the place to see if i could get the RPMS to jump, there was nothing, did an eye inspection still aint seeing nothing.

the vacume lines are all good, i dont see anything really that has any cracks or sounds like its leaking.

but here is a video of what im trying to say, oh this is running slightly cold, but its the basically the same thing as when its warm. oh and it only does it when im pushing the car hard, or to the point of where the turbo is spooling up. inbetween shifts it feels like turbo lag, then the turbo kicks in and then weeeee here we go again. well try to imagin the bov releasing but not closing all the way untill the turbo kicks in again, you have a boost leak. so it drags along then it flys. i think i explained this problem pretty good
oh heres the video.

idle drop
