The only code for the check engine light I get is that I need a new o2 sensor because it's bad, I ordered another 1. All we used from the 25k miles engine was the block, and everything else was used from the old engine that locked on me. we used same coils and plugs from my old engine, but I had just gotten new plugs for my old engine a month before it stopped on me.

May I ask, "what was wrong with the original engine?".
