I have a 92 cavalier 4dr with a 2.2 auto. When i go to start it, it runs really rough till the temp rises just a bit n if it sits for a week or 2 it wont even idle without feathering the gas. I was thinking maybe idle air control but i have no clue. Help...
How long as it been since its had a tune up?. Could have a Carboned IAC motor, Could need a fuel filter replaced, thermostat may also need replacing, Have you had a pressure test done on youre fuel pump, Piston cyl's compression done?.
