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.

Check engine light on was told air injector valve oper/solenoid replace. Drove 800 miles, took emissions test failed. Showed no codes. Was told by tech to try driving 100 miles. Or take to dealer, took to dealership charged diagnostic fee. Was told by them to drive 100 miles. Drove 150 returned next day. Still the codes are not showing. Want me to drive another 150 miles. Two codes are not showing. Took back to emissions provider, they showed me it was the 02 sensor and last test on the obd computer. I don't remember the name. Also please note my radio froze again playing on 1 station and showing another. Showed it to tech today. And also my brakes still giving same problem. ABS brakes still pulling vehicle. Bought new tires to help with the traction. But problem still same. Fuel was about 12 miles per gal. How many miles do I have to drive in order for the computer on the vehicle to respond. I've driven over 1000 (one thousand) since Friday 10-21-05. What a lemon! I will be returning back to the dealership (chev) tomorrow after driving 150 miles. My daytime light still goes out when using turn signals.
