I just bought my car used in January 2008 and the check engine light has been on and the car is hard to start. However, the car did pass inspection because the problem that I'm having isn't considered failing during inspection. I took the car to be diagnosed and the engine cool packs all had to be replaced. After the parts were replaced, the check engine light is still on, the car still shimmies and it is still hard to start. This happens everytime I start the car!.
Rough idle and check engine light comes on at times. This car only has 33k miles on it !!! dealer says this is normal for the 300m special.
