Ok car was fine no probs. SO installed a emanage, and z32 maf, car is still fine. Then i install greddy intake and redo the piping and now the car bucks and jerks at light throttle. I checked the tps. And im not hearing any boost leaks, but at 1000rpm (m new idle speed thanks to this problem) my vac is at 10-15 and not the normal 20. Will just a tiny vac leak cause this much of a problem?? thanks guys, its late im tired hook me up with some help. Tomorrow i may have it figured out but i figured I would ask just incase someone has had this happen to them also.

the smallest leak in the IC piping can cause the car to buck.

Well its fixed, come o find out it was my electric fans. See i have a top mount turbo with a short pipe the the maf then a filter. And the fans were blowing air at the maf throwing the voltage way off. I just converted it to a blow through setup and now it runs great, honestly it runs better as a blow through than it did stock. Very very responcive just like an all motor car.
