car shutting off


Asked by Oct 16, 2014 at 03:43 PM about the 2000 Buick LeSabre

Question type: Maintenance & Repair

I have a 2000 buick LeSabre limited and when I first start it up it cuts off before I go 3
miles but then it is fine and runs great. I've had 5 people look at it and can't find the
problem. Help

Throttle position sensor? Or there might be a film build up on the throttle plate itself. It won't close all the way then. Take the rubber tube off between the air filter box and intake, clean it off with carb cleaner.
