My '03 Trailblazer has a bad PCM, I took it to my mechanic he took a look at it, he referred me to another mechanic that does specializes in PCM I took it to him and he's booked until next week. I was doing some research and I found out that PCM can be covered by the Federal Emissions Warranty for 8 years or 80,000 which ever comes first. I bought the truck in 2010. So it is covered or not. I just want to confirm it .
