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 2001 Bonneville misfiring & running rough, it sounds like a tractor. my wanta B mechanic did a diagnostic on it, he said I needed coilpacks, so I put $85.00 coilpacks on, still runs really rough. next is plugs n wires. but I want the designer of these dang sideways motors to come n put the back 3 plugs n wires on for me.
