Ok so I have a 1981 280zx with the 83' turbo motor in it and so far the car has been running decent and getting better everything is stock except the fuel pressure reg, front mount intercooler, and BOV greddy. I was driving the car last night and the car does something really weird i will floor it and the car will bog like it has a boost leak or something but wen i hit a turn or a hump on the highway it goes away and the car takes off like a bat out of hell and it returns back after a lil bit on the straightaway. What could cause this? I was thinking maybe sensor? My friend Was Saying Maybe a Short Or Fuel Pump?
