Well, I'm not quite sure how air is leaking into the exhaust pipe, however that's what the inspection performed by the people who put ON the pipes said was the problem. I've only personally noticed the light come on during long driving periods and/or certain weather conditions. I've yet to put it up on a lift myself to verify the problem, however.
Thanks for the vote of luck, i need it. =)

True, However don't those codes come with the All-data information system? I seem to remember the system having that information.
Either way about it, any shop that works on brand-new cars should be able to purchase the computers from the manufacturer that gives the necessary information.
I've been training as a mechanic and in most of our classes we use computer diagnostic tools as one step in verifying the problem.
First off, while the error codes are usually VERY accurate to what POTENTIAL problems are, they DON'T always tell you exactly what the problem is. Case in point: '96 GMC Yukon, the Service Engine light comes up every few days. Running the computer codes, it spits out a problem with an O2 sensor in the exhaust system, saying there is too much O2 in the exhaust. Now, this could be a number of things wrong...from problems with plugs and whires to bad gaskets, etc. that allow O2 leakage. However, the problem is nothing more than a crack in the weld on the exhaust pipe that leaks air into the exhaust system before the sensor, causing it to go off.
Secondly, last time I checked, I could buy manufacturer-specific computer equipment to diagnose cars from the manufacturers as a mechanic. Yes, the're about $600-700 a pop. (Snapon in turn sells a computer for that price and sells modules for each manufacturer for diagnosis).
Also, these performance maps and such you think aren't necessary...are. Why? because, during diagnosis, one of the things we look at is engine performance to verify that the engine isn't having trouble. The computer calculates and spits out performance data for the technician based on the information in the computer. No, we don't get to see all of the information on the chip directly, but for the sake of diagnosis, our tools have to be able to access it in the event that the car's performance is lagging behind what it should be and we have to diagnose it.
maybe i'm wrong here, but isn't this the design that Apple used for the G5? i mean, seriously, from what I've seen of the G5's innards, it's doing exactly this: pulling air through the case. Only difference i've seen is that the G5 maintains a tower formfactor, and the biggest airflow goes through vents over the processor heatsinks to dissipate the heat, then forces air through the back and out. The biggest concern I have with either design is how the disk drives are nested, and how the HDD is kept sufficiently cool.

Thank you for our time.
