I'm not 100% sure about this one but here is my educated guess.
Some engines are manufactured with a special vacuum in them that allows them to pass california emissions. It's basically a way to pump air into the exhaust to fake emissions. I actually have this on my Monte (But I don't know if my Monte was sold CMI) It doesn't effect any performance in anyway, it's just something extra that GM uses to fake things. Not all engines have it, so maybe CMI just refers to that?

So did my '83 2.2 Dodge Charger. Every so often the stupid thing would burn up and once again I was at the salvage yard trying to find a working one that would mount up to my engine.
I have no idea what these pumps are actually called? I always referred to them as a cold air pump and other people seemed to know what I ment.

the car was on e-bay for $2600 and now it seems to be gone? i sent e-mails for carfax and other info and received that but the last e-mail i sent hasn't been answered, so i'm guessing the car was sold!! which sucks for me, again!!!
