Charcoal canister affect gas mileage?
All stock 87 GTA with Bosch III injectors and flowmaster exhaust, no cat.
I've removed the smog pump and had temporarily removed the charcoal canister.
Would this have any large affect on gas mileage? It also seems since I recently put the exhaust on, my mpg dropped a bit?
Filled her up maybe 3 days ago. So far have put 80 miles, all city, and I'm at about half a tank.

Re: Charcoal canister affect gas mileage?
To my knowlege, I know the canister affects emissions, but i dont believe it affects mpg much, if any at all. I may be wrong though.
As for the exhaust and getting worse mpgs, is it possible your driving a little more "heavy-footed" now?
lol
