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.

A year to date my car is back in the shop becuase I thought the same problem was happening with intake manifold. However, this time it is just the cylinder misfiring which could have been a result of the intake manifold cracking and water getting in the cylinder. I just read on this home page that an upgraded probe into engine fires of the 3.8l V6 is being done. This does not surprise me. This is a poorly designed engine and GM should be ashamed of themselves for putting out a product this poorly built. I foresee future problems to come and will be getting rid of my vehicle ASAP.
