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.

problem #3

Silverado 2500 2WD 6.0L V8

The engine light would flash anytime I was above 50 mph, throwing a misfire. I plugged in my code reader, and it showed a misfire on every cylinder. Replaced the Spark Plugs and wires, nothing. Fuel Pump, Nothing. Mass Air Flow Sensor, Nothing. Air filter, nothing. Still throwing a misfire...
