I want to take the emissions junk and charcoal canister off my '92 firebird 305 TBI. I am just wondering how hard it is, and what exactly I need to take off or plug up, or whatever so it doesn't screw anything up!

 

Hey, how's everything? I'm in P'Cola as well.

It's not too hard to remove the emissions equipment, just time consuming if you're impatient. The main component and first thing you'd remove is the AIR pump. Here's an article on removing it that would apply to a 92.

Then you start following hoses from that unit and pulling them out. It'll go to the AIR divert valve. You can just unplug the electrical connectors and tie them out of the way somewhere. Then one hose goes to the AIR port manifolds on the exhaust manifolds. You can remove all that, and plug them with brass plugs that you can find easily at a hardware store. The other hose from the valve goes down to the catalytic converter. You'll have to remove some hard to get to bolts to get the hard lines out, and will most likely have to cut the connection at the cat (it's usually so crimped you can't slide it off). If you think you might ever reinstall it in the future, then instead of cutting it across the pipe, make a cut lengthwise along the crimped area so it'll expand enough to slide off. That way it can easily be rebrazed or welded back on later.

Thanks for the help, and thanks for the welcome!
