Have the secondary air injection fault code. pump runs, and shuts off as it should...should it run intermittently too? any suggestions?

Mine went down and I just replaced it.

But, to the best of my knowledge it runs when the engine is cold for 90 seconds and that's it.

Well, I have cleared the code a few times, and it keeps returning, so it wasn't an isolated event. I heard the pump kick on when the car started, the it fired up about 10 mins later, after idling for a few mins in a drive through...what commands the pump on?

Oops wrong thread; MBWorld’s stupid “related” thread causing me headaches when I scroll to the bottom and reply to that.
