Check your IAC steps at warm idle - it's under the Dashboard menu on the handheld. Mine originally was in the 50's, needs to be between 3 -10. Have to turn the idle air screw at the drivers side front of the TB clockwise to lower. Do it with the engine off, then start and check the reading at operating temp idle. Adjusts all have to be made with the engine off.
I'm not as concerned about the canister but I wonder about vapor lock between the mech fuel pump and canister. One of my winter projects is to re-route the line to a cooler spot.

My IAC's are right around 10 when warmed up. I've already adjusted them. One of my theories is that as all the gas boils off through the vent tube, an air pocket gets created in the high side fuel pump, then when I turn on the key, it fills the FCC can, then starts and there's an air pocket slug that gets to the TB and it dies. That's just a wild theory that I have. I'd like to get an in-tank set up some day.
