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.

At interstate highway speeds and towing, I get a Check Engine light flash then stay on. "Multiple Cylinder Misfire" code come up when checked. I changed spark plugs, plug wires, dist. cap, and rotor. Fuel pump tests ok. Still comes up. Changed fuel filter, air filter, and used 2 bottles of fuel injector cleaner in 2 different tanks of gas. Still comes up. At regular speeds with no load I don't have any problem. When the tach gets over 3000 RPMs, the problem shows.
