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.

It was raining hard in our area( 1 inches in 1 our). I live 3 miles in on a county dirt road and it was muddy with standing water. When all the water and mud was splasted in the engine compartment the was idleing rough. This is the (2) second time this happened. The first time was about 2 months ago in April when we had same type of weather. Took the car to my dealer service dept and was told they could not find nothing wrong and that I had water in my gas. I put atleast two bottles of dry gas in tank. Car ran fine until the eveing of 6/14/03 when again we had alot of rain and the same 3 mile wet, muddy, standing water dirt road.
