Need Answer For Cold Start!

[GTR34-Vspec]

Hi guys, my GTR have been having problems with cold starts ever since I got my air flow meters recalibrated. What are the potential causes of this problem and how can I fix it.

By the way, does anyone know what the normal idle rev for a standard GTR 34 V-spec as my one is around 1.1 X1000 (is this normal?).

Cheers!

950-1000 rpm , how do you know its 1100 ? Are you going by the the stock tacho or power f/c ? Stock tacho on the 34 at low rpm is not accurate .

On cold starts it should be higher by 200-300 rpm , what problems are you having low iddle or high ?

The RPM is just above 1000 on the stock tacho (either cold or warmed up). I'm concern that it is too high.

Idle speed is controlled by the computer. Which controls a little stepper motor near the throttle body. Maybe its full of crap, and is having trouble travelling to its full limitations. Other then that the idle speed has been set by the tuner, and thats that.

Thats about right when normal operating temperature is reached . It should be higher when cold and when air cond is on . Do you have aftermarket computer ?
