hey guys were finaly about to drop the motor in to my Z but we still got some work to do. 2 days befor the accident we did the intake manifold swap on the car, in those 2 days we ran into some problems with the car. during normal driving all electrical power on the car would cut of and sometimes it would even stall. the problem seemed to happen around 2k-3.5k. i was wondering if it possibly had to do something with the opti? or perhaps something else? thanksss
