Making lemonade from a lemon

I ended up with a 2012 chevy cruze. I was helping a friend, saw nice looking cruze and bought it. At the time I was overwhelmed by things in going on in my life. So it was a rush buy without really going though my good look over of a used car. The car I thought was fine, slow but nice. Then of course engine light came on, and tire pressure sensor. So after I finally got life under control. It was time to fix the little cruze. Check engine light. Mass air flow sensor. Changed it and came back. That's when I noticed a lever not hooked up under turbo heat shield(waste gate actuator),then also noticed turbo solenoid plug off. Connected both, and wow car had some power now. Check engine light gone for now. Don't know why or how got disconnected, but have noticed whoever worked on this car wasn't such a good mechanic. Tire pressure sensor, all I can say is buy ac delco part, the cheap replacement no good, lesson learned. Check engine light again, evap leak, low cat efficiency, and lean bank 1 codes. Fixed those, and going well now. I'm actually liking the car and was going to sell it, but instead I'm going to mod it and make lemonade. I have mod build on different thread on here.
