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.

The catalytic converter has been damaged and needs to be replaced. The repair shop says that the damage was a result of unburned gasoline going into the catalytic converter when the coil failed. The coil assembly failed and two cylinders stopped firing. I only drove the car about one-mile to the repair shop after the failure (which happened suddenly). The coil assembly had to be replaced at a cost of about $400. After it was replaced, the "check engine" light came on and the repair shop says that the on-board computer diagnostics indicates that the catalytic converter has failed. The car cannot have its registration renewed without a functioning catalytic converter, which will cost about $500 to replace.
