It's not restrictive in any way, leaving it attached won't cost you any power.

Adr27a can't be right as the vs (well after 1976) comes std without egr, don't know what's going on there?

EGR = exhaust gas recirculation. You're right, the VS doesn't have EGR, but the charcoal canister doesn't deal with exhaust gasses and neither does the PCV.

Is this really possible? Im pretty sure that back in the 60s or something all cars had vented fuel caps to stop the tank from over pressurising.

Pretty sure back in the 60's the fuel wasn't quite as well refined and volatile as it is now.... but really the carbon canister makes 1/10th of sfa difference to the engine running, it's only there to relieve vapor into the engine instead of vapors hanging about elsewhere, there's no pressure relief in a sealed efi system is there? kinda figured it was sealed for a reason, but it is a commodore so anything vb-vs the vapor lines will be ####ed anyway.
I actually miss the pre 74 cars i used to own but the smell of fuel, (lack of heating and aussie ac) I do not miss since the phase to lrp and then nothing but ulp, actually had to drive them..... ah nostalgia.

Was just pointing out that that design rule isn't right

Can a faulty canister cause the motor to stall at idle?
I’m chasing a “ stall and won’t start again for hours” problems... it’s doing my head in! Fuel pump seems good and doesn’t throw any fault codes on scanner ‍♂️♂️♂️

I doubt it. Sounds more like a CAS, if V6. If it's a V8 then there are a couple of other common problems that make it not run.

Thanks mate
It’s a V6 and CAS already been replaced and not throwing a code
It will run occasionally and stay running if you’re giving it throttle but dies after about 30sec on idle

Could be a TPS. Sometimes CAS won't throw a code and same with TPS.

I agree with Losh, TPS sounds like the culprit.

If it happens 5 minutes after starting engine (when purge valve opens), perhaps there is a vacuum leak - hose off?
