a very annoying fault code on my cobra, p0411 secondary air pump incorrect upstream flow detected. does anyone have an idea what is going on with it? it seems to be this time of the year that it comes on, when i first start the car it doesnt have the code like other drivers seem to have, its only when the engine is warm, the car is stationary for more than 10 seconds it will pop up. its only done it since i changed the tune to the stock tune a few days ago. the code now returns whether i have the stock tune, diablo tune or custom tune on the car. i have no mods, its factory except the diablo tune. anybody have any idea where to start with this? im completely clueless.
