Car Updated

So I brought my car into the shop again on Friday and it was another sensor. The dude told me that typically the sensor's last until about 150,000 miles. However, my first sensor went a few months ago and he thought it was a fluke, so he didn't replace the other one because of this. So...he replaced my other sensor (no charge for labor yay) and he said that my car is really good shape and should last a long time more. SO..I am going to hold on the new car for two years, only if the damn check engine light doesn't go on again!!
