Ok after studying the evap system. I decide to pinch off the hose from the breather valve just before it goes into the intake manifold. Started the car and it rev up and down for about 5 seconds and then stopped. Idle was about 2000 rpm but then again it is like 5 degrees Fahrenheit here. I let it run for about a minute and the idle started to lower itself, but it start reving up and down again. I think I need to reset the computer
