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.
