When i start my car, cold idle- it revs up to 1.5- 2000 rpm then in about a minute or so the rpm's drop down like crazy, it either drops to 400 rpm or just dies. When i drive the car and once its warmed up, it stays at normal idle at 1000 Rpm steady. Can someone help me out with this problem so i can tell my friend whats wrong!


heres the video

It will interpolate the idle speed between these values for a steady drop as the engine coolant temp rises to operating temperature.

Another thing to check; make sure you have coolant lines running to your fast idle valve (on bottom of throttle body).
