My friend's 92 Camaro has a problem with rough idle only when warm.
His mechanic disconnected the wire going to the charcoal canister and
now it runs OK. Any idea what the CORRECT FIX is, rather then
disconnecting that wire?

There's a wire going to the charcoal canister? What would that be for?

For the idle issue, has he checked for vacuum leaks?

I have no idea what the wire is for other than a sensor or solenoid. I
haven't looked at the car yet and we have no manuals or diagrams
yet...hope to get a GM manual in a day or two.
After his mechanic disconnected the wire it runs fine....but why?
That's what I'm asking you guys for.
Thanks

Does the car have Federal or California Emmissions package? What is the
engine vin code?

Just a thought. Maybe he's talking about a wire to a solenoid that
opens/closes vacuum to the canister for emissions. Is it possible that he's
got a leaky hose or something to that effect? Could be the problem is a
vacuum leak (as someone else mentioned) caused by leaky emission hosing.
Removing the wire could be taking the that emission system out of play.
Good luck.
