2003 Mazda 6 6 cyl Front Wheel Drive Automatic 84000 miles
For the last 6 months, I have been getting billowing white smoke from my tailpipes during start-up and sometimes at idle. However, it doesn't happen all the time. For example, It would happen for 2-3 days, then it would be fine for 2-3 weeks. I have taken it to the dealership and they replaced the throttle body, throttle body gasket, and intake hose. It still did not fix the problem. I don't have any coolant loss, I have bad gas mileage. Recently, the car would shake at start up.
