My dads 2006 chevy ssr died on me today. I had to push it back home. The truck before it died lost horsepower it went from 400hp down to 350hp and that was it. I shot the throttle body with ether and it did what it was suppose to do it fired off and then it turned off. The two engine lights came on. The one was the engine light and the other one was loss of power light. I put my tester to the computer and got these codes. The codes are p0443, p0689, p1682, p2101, p2176, c0700, c0300, p0102, p0113, and 3-5 N/A code not sure what that means. The battery has been tested. It is good they could not test the alternator but they said since the battery is good so is the alternator. Thanks.
