P0410 code, something else has to be wrong.
I have an 04 trailblazer lt v6. Last week a light came on the dash that said something like "reduced engine power". It then kept stalling out on me. I had to ride the breaks and not come to a complete stop all the way home. Checked the trouble codes and P0410 came up. I checked the fuses and power relays for the AIR system, all good. The check valve was not doing anything when hooked up to 12v power so I replaced that, same with the smog pump. Now it will start up okay, rev pretty high, then cuts out. I read somewhere that this may be from the battery being disconnected. I read that I needed to clean the MAP (under the plastic cover that says "4.2" on top of the engine). Did that and it is still stalling after a few minutes of idling. I'm at a loss for what to do now, any suggestions?
