Well, I replaced the air injection valve on Saturday (quite a knuckle buster), cleared the codes, and all appears to be well. The old valve could not hold a vacuum, so I am pretty confident that this was the source of the problem.
Thanks again to all who provided insight into this.

Hi Geoff; I appreciate all of you on this forum. I'm a new member and new owner of a 97 Boxster 2.5 with 44.000 miles. My CEL is on (learning a lot) replaced the MAF sensor before I bought an OBDII scanner because the MAF issue did not fix the problem. I discovered that I have one error code P1411 ( Secondary Air Injection System-Signal Implausable, Cylinders 4-6).
I was curious to your success, since you said that you replaced the air change over valve. I am about to tackle this job myself. Is this a DIY'er ? I know I need to check hoses for vacumm leaks first. Is the only way to get to this valve from above the car under the top, or can I get to the engine from the back seat as well?
Where did you find your air injection system parts ? Do I have to order them from the Porsche dealer. Any help or insight as to the P1411 error, and what area/part do you think I should check first ? Geoff, or anybody!
Thanks; Alan!

Hi CJ;
I had this problem with the cel light a year ago, descibed in my previous post, replaced the Maf sensor hoping that it would fix the issue. It didn't fix the cel light problem, so I bought an obdII scanner and found a P1411 error code. I cleared the code and the cel light went out, only for a day or two and came back.
The P1411 refers to a problem within the secondary air injection system. Thanks to Loren's diagram, that shows the secondary air system, hoses etc. It is located beneath the plenum on the right side of the engine, looking down over the right rear fender. Without the proper tools and the system being hidden under the plenum, not sure if the parts would fix the problem, I took the car into a reputable German auto repair shop in the area. Here's the deal; I explained to the technician what I have learned from Renntech, and after diagnosing with his obdII scanner he found a P0410 and a P01411 my sensor only picked-up the P1411 error code. Turns out it was the a bad air change over valve #2 and # 3 electric change over valve (Loren's diagram). The hoses were replaced due to possible leaks. The air injection pump was fine.
It wound up costing me $ 600.00 however the aggravating cel light has been out for a year now.
