Its a 2.2L Duel overhead cam. And the idle is low,(500RPM), while in park it vibrates the dash, and while in Drive it will vibrate while at a stop. If I step down on the gas a little, It will completly get rid of the vibration. Is there a kit I can get which will adjust the idle? It has an internal distribution system. Idle should be at 600RPM And the car is completely tuned up. Oil change, air filter(cool air intake) fuel filter etc. Any answers?
