The car cranks and runs a lot better, but still building a lot of fuel vapor pressure in the tank. It seams to be worse the lower the fuel gets. Next I’ll try a fuel vent.

i would get someone to look at your 1991 camaro and have them to make sure that everything is hook up right and get it tune up as well

Lol - how can you tell if you're getting poor performance out of a 3.1? Doesnt it come with poor performance standard from the factory?

When it’s worse than poor 🤣

If your canister is clogged, disconnecting and plugging the line would result in the same engine performance. My money is on your ignition control module overheating.

I plugged the vacuum line and put an air filter on the vapor line. It cranks and runs much better now. Removed purge valve and an no longer connected to canister.
