Can any guru/mechanic here in Nova help with P0411?

Hi,
I've recently bought a 2000 s2k hardly a month ago and already have a CEL throwing a P0411. I'm personally not very tech-savvy and followed numerous threads online to check for all the leaks, abnormal signs etc. Any recommendation for a good s2k mechanic in Nova area (I'm in Falls Church) ?
Much appreciated.

P0411 = Secondary Air Injection System Incorrect Flow

You are likely to have one of these issues:
Vacuum hose leak (most likely IMHO)
Blown Fuse #6 under dash (15Amp)
Bad Air Control Valve Vacuum Control Solenoid Valve (located under the air filter box)
A short or open wire.

The easiest is to first check the fuse under dash.
Next easiest is to check all of your vacuum lines.
Then installing a new vacuum solenoid valve (also fairly easy)
For the rest, take it to a qualified technician.

Does this car have a cold air intake installed?

Yes. The previous owner did install a generic CAI, but he also mentioned that the CEL didn't come on immediately after the CAI install.
