Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I have a 2002 Chevy Prism that seemed to all of a sudden began to get really poor Miles per Gallon. I was getting no more then 200 miles per full tank of gas. When I first got the car, I was getting 320 mpg when not using the a/c. and quite a bit over 200 when using the a/c. I took it to Auto Zone and had it checked out. Next thing I did was purchase a O2 Sensor that cost $100..and around $69 for the garage. That helped the mpg a little, but still it was no where the way it use to be. Next my Niece replaced the spark plugs which cost about $30 with a $10. rebate and paying the niece $20 to put them in. (It was a first time for her and she did it fine.) This did the job. Of course I do not get as good of mileage as I did when it was considerably way lower mileage. And when I am not using the a/c, I have decent mileage. I do believe it may not have needed the O2 Sensor in the first place.
