I like mine, too. After my new O2 sensor and plugs, I started getting the Check engine light. Arthur helped me troubleshoot, and ended up that reseating a few vacuum lines cleared that up. Now the car runs really well. As I now have a) new wiring harness, b) new head gasket and c) new AC evaporator car I hope to drive it another 100,000 miles.
