Anyone knows anything about code P0411?
The code is: The secondary air injector incorrect upstream flow detected?
Is this easy to fix, what does it take for me to change it and is it expensive?
WOW, got the car all put together (alternator, orl cooler box)the engine light went away and it came back with this..........help!
excuse if i miss spelled something, i had to type quick, before my boss comes out.

If you edit your post to only have caps in the correct locations, I will answer your questions.
Typing in all caps is the one of the quickest ways to **** people off in this forum.

Yes, searching the forum first is recommended here, but to answer your questions...
The P0411 code comes from the secondary air injection system (SAIS) going awry. Each component is quite prone to failure, and in my case, all buy one solenoid went bad. The combi valve, secondary air injection pump, N249 and several vac lines all went bad at one point or another. Search for those items for more info on them.
There's two things you can do: replace all of it (you may as well, b/c it all will fail at some point) or remove all of it. The later is what I did, and I put together a write-up for it. However, I need to make some corrections and repost some pics, but you can still look through the post if you want.

Been too busy with school to start playing with the car yet... Ordered an O2 sensor for starters,
but I'll fool with the rest after finals. Goal for the summer is to have it all replaced/upgraded.
