Thank to all your respond, i really appreciated it.
First of all, yes mad082 im mean 6000 rpm.
I took it to the Mechanic, he checked the computer, test OK (Has been reset as well). Checked fuel crank angle sensor OK, checked in jector pulse OK, checked fuel pressure was low 40psi on full, replaced secondhand fuel pump and rechecked 50psi OK. checked boost controler OK we wll
First i thought it was a traction control as well, but this each time this happens my head almost hit the steering wheel O_o. Pull the car so hard.
I paid $145 for the second hand puel pump and $70 for labour. I still have the problem.
@Clutch those steps are reasonable. Ill double check with those when i have time. On top of that i asked a guy who used to have R34 GTT as well, he said he had the same problem and it was the spark plugs. he said go buy 6 of them from Nissan dealer and change them. That was how his GTT got fixed. I still have a high doubt that it will fix by changing those spark plugs. O_o
Kindest Regards
Charlie
