1997 gtp engine light

I recently had the engine light come on, so I took it to the garage and they told me left bank was running lean. Also said it could be a bad oxygen sensor. Before I go out and start replacing parts I need to know if anyone has any other ideas. The car also has a dark colored smoke that comes out when I first start it in the morning. While it was in the garage I had them put on a 3.4" pulley, would that have anything to do with it.

It would be nice to know what code the scanner pulled up.You wouldnt happen to know????It should be P****

IIRC you had a secound post on this and said something about a injector was leaking....that would be the first place to start.That would cause a lean condition.You can also pull that plug that has to do with the injector and see how the plug is burning....if it is very white,it's time to replace the injector.
