Vehicle: 2002 Toyota corolla 1.8L automatic 4 speed, 58000 miles
Story Part 1
On the night of march 12, Thursday, I overfilled my gas tank as I had been doing for the whole past winter which had been extraordinarily cold.
I am not talking 2-3 liters. I am talking about 15 liters every time. I would meticulously pull the gas hose and wait for the frothy bubbles to back down into the tank, pump more, repeat.
On Friday, in the morning it was -10C so i had no trouble driving to my carpool lot. On my way back home, the car started to stall when hot.
Driving cold = OK.
-Give gas, let it coast, stall.
-Come to a stop light, rough idling, stall
Story Part 2
Got the car towed to my mechanic on friday night. Saturday morning he said that no error code was present. But running with MAF disconnected causes no issues and it runs as normal as it always does. So I replaced the MAF sensor ($275) from the dealer. No difference - stalls. Disconnect the MAF, everything's good.

Story Part 3
Drove MAF-less to the dealer for help. Paid $116 for diagnostics. No error code. Dealer mechanic cleaned throttle body, checked every sensor. No issue could be found with any of the systems. But you connect MAF and the engine stalls.
Dealer Mechanic drove me home. We discussed my overfill and he said BINGO!! Your charcoal canister is designed to screw up with an overfilled tank. The only weird thing is, you have no error code like P0441 or P0446 etc.
Story Part 4
Monday, Tuesday (Today), drove to work MAF-less. No problems otherwise with the car.
A mechanic friend says "You could try for a dry off but good luck with that". After throwing $400 at it, I have no idea about what may be wrong. Where should I go next? what should i check for? which parts/systems should I try to disconnect etc? Would you advise against buying a used charcoal canister? Am I bound to fail the e-test next time? Am I harming my engine running MAF-less? Fuel economy is exactly the same still.
