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.

I was driving when the car start to accelerated by itself, accel pedal went to the floor. I could not keep a car even by the hand brake, so as it was jumping ahead. Then the car began to blow black and white smoke out under the hood. Some how I turn off the engine, took the key and run away from the car in the middle of the traffic road. Green liquid under the car. It died on the road. Police came, the car towed. After several days of checkout : T/3.8 checkout and replaced T-stat, temp sensor, T-stat housing gasket; bg coolant flush ; PCV; engine vent; engine mechanical; bg power steering; bg brake after a week I got the same--jumping, not stable, accel pedal goes to the floor. Internal short in cyl 3 and 2 coil and fouled sparkplugs T/1.5 replaced coil pack for cyl 3 and 2 and replaced sparkplugs.
