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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

My first trip to the emissions repair facility I had the gas cap replaced. The code for an evaporative leak was cleared. After filling my gas tank and driving about 300 miles the Service Engine Light came on again. I went back to the emission repair facility for a second time and they still thought it had to do with an evaporation leak in the fuel system. They replaced my filler tube this time and cleared the code.

After purchasing my 2004 Chevy Trailblazer Ext. in Florida and bringing it to Virginia where I live to have it inspected my Trailblazer failed Virginia state emissions inspection. The inspection report showed an evaporative leak which was thought to be caused my an old and worn gas cap. The inspection station referred me to an emission repair facility to have it checked. The emission repair facility checked the code and suspected it was a bad fitting and worn gas cap as the inspection station thought. I was given a new gas cap and the code reset.
