how do you adjust the idleing. i know there's an adjustment screw, but don't cha got to do something else beside that? when the car is at low idleing,the motor shakes a little . any advice or anything. thanx

 

Go to the FAQ at the top of this section and download the factory service manual for your car. The detailed procedure for setting the idle is in there. It's a bit more complicated than just turning a screw.
