I have a 2004 Blaze. My service engine light is on and when a scan is done I'm told it's a secondary are injection malfunction. I took it to the dealership and they told me that I need to replace the air pump, the O2 sensor, and the air pump relay. Now I'm havine a difficult time tracking down this air pump. any ideas? Thanks.
