Hey,

I had this porb when i first got my car.

It may be your cold idle sensor is closed constantly.

Because what normally happens is when the car is cold the sensor opens up and makes the car think the throttle is open a little bit. Thats why you'll usually idle at 1,400 rpm or there abouts.

Yet yours may be constantly closed which would explain why its fine when it warms up.

You can get a new idle sensor for like $50 i know a guy if you need help.

Hope you can understand my poor technology explanation

Hi Sherrif;

Do you think the reverse may be true if warm idle at start up is really lazy? When started warm my 32 GTR fires and runs but revs are slow to build from about 550 - 950. Idles OK once they're at 950 though. Doesn't happen when cold.

Cleaned ACC valve but no joy, any ideas?
