So, this is technically my first lightning that I've bought myself, my other lightning I inherited via my dad, that has a built 4 bolt mains, the works. I saw a 2000 on FB marketplace for 15k, drove it, it runs really good, so I bought it. However I have some concerns with it, it has 209k miles on supposedly the original drivetrain. As stated it runs really good so I have to assume it was maintained to a degree. The truck has an open air filter, and no cats upon first glance of modifications. I got an engine light and checked it, bad pcv. But as I was going through all the obd data, I noticed the truck is running 17-20 degrees of spark advance?? I thought that's a little high,. I've been running pump 91 since I got it. Otherwise the truck has treated me well since I got it, no complaints. Just wanted a second opinion on this stuff?
