its a vacum leak my car did the same thing it was the vacum line that goes from the bottom of the upper intake down to the vaper canister on the right lower side of you car.. The vacum line runs behind the distrubitor and burns right there...Pretty sure thats it check that before u buy sensers u dont need like i did... [Smile]

Outside of a obvious vac leak, check the MAP/Baro sensor. When cold, it isn't reading correctly, causing the car to go full rich...killing the motor.
