If my check engine light comes up with P0411, is that a "fix-now or more problems will occur" type problem? I am not ever 100% sure what secondary air injection does... thanks. jered

Re: P0411 = annoying and/or harmful (Jered96VR6)

The system blows fresh air into the exhaust manifold during cold starts - keeps the ozone clean. It's more annoying than necessary, but some states require it to be in working order. It won't damage the engine, afaik. I had the same code/problem last year which was caused by a broken vacuum line to the system valve. Check the lines and the fuse.

Ok, quick technical question. My light is still on and the stealership says that the valve is stuck open... so does that mean that hot exhaust is re-circulating and could possibly decrease HP and cause a slightly rough idle?? thanks. jered
