The service engine soon light comes on and we get a Secondary Air Injection problem when they read it at Autozone (not sure what number code). Its a 2001 S10 4.3L 4wd, anyone have any ideas on what to do?? This is the second time it has happened and they just clear it....

If you have a P0410, you almost certainly have water in your SAI pump. Common problem. Just crawl under there and pull the hoses off and water will probably come out. The pump is right near the radiator in the center of the vehicle, underneath.

Knowing the code will help greatly to pointing you in the right direction.
