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.

This problem appreared around 100,000 miles. Car would idle roughly as RPMs dropped well below normal when car was in gear. Usually worse with A/C on. Replaced too many parts to list, but here's a few: Both O2 sensors, Idle Air Control Motor, Spark Plugs, Wires, etc... The final fix turned out to be the fuel pump assembly. I had to purchase this from Mazda as the aftermarket ones are not the entire assembly and are visibly inferior. Once this went in, it ran great again. Milage is now in excess of 166,000.
