somethin with your idle. I have a carb and if i turn my idle control down it stumbles. Maybe you are not getting enough fuel at low rpms. I dont know about the fuel injected cars, but not enough fuel is prolly the problem. Maybe injector problem.

Change your plugs/air filter/fuel filter and your oil.
