Its overheating.... or the wire shorted
300zx twin turbo lots of black smoke and running rough
It is the control box under the dash
one of your light is not working happen to me
I have 255,000 on a 1987 Nissan 300zx and still running strong. As long as you maintain the car and change the oil evry 3000 mi it should last a long time.
you just move the flaps around
I've heard u can resolder the ground inside the control box but your best bet is to just replace it.
check you ecu under the kick plat on the pasanger side then you might have to change you ptu
It is near the first spark plug on the passenger side almost hidden under the intake plenum
300zx from 84 - 88 are z31
Make sure the radiator fan is working.
I would suspect the fuel pressure regulator.
theres one under the hood near the brake booster silver can with two lines running through it.
