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.

4 or more proposed solutions from various mechanics. Buick dealer finally found it after I ranted and raved that they are the experts. Told them to call Detroit if they had to. They told me the catalytic converter had collapsed, causing backpressure in the engine. They figured out by disconnecting the manifold from the engine. Once they did that, the engine started immediately.
