What the heck is it and how do I know if my 2001 LT Tahoe has it?

A.I.R. = Air Injection Reaction...system to inject air into the exhaust to reduce tailpipe emissions
You will have a pump and some hoses going to the exhaust manifolds.
The pump is an electric unit located on the right fenderwell near the firewall
