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.

Loss of power, surging, so I took to dealer they changed fuel pump supposedly and filter and transmission fluid. One week later I took it back because it continued to do the same, they said they checked a wire to fuel pump and changed a spark plug, and here it is another week with the same symptoms.
