Engine Mechanical problem
2004 Toyota Corolla 4 cyl Front Wheel Drive Automatic 172000 miles

i've had my car since brand new, it's high mileage, and no problems till this point. My girlfreind put gas in it and I smelled gas after stopping every time. Now check engine light comes on, I tightened the fuel cap, until it clicked gas smell has stopped but had the codes read, the autoparts store code reader says evaporative emmission control system vent control, or poor electrical connection, or faulty ccv? Vent control solenoid. Or evap line leakage, or pump module failure, or canister faulty, amongst about ten other " suggestions" where do I start? And what am I looking at? And where? Light is still on and every now and then I get a sputter, especially when it's cooler.

A loose gas cap will cause the codes. Have the autoparts store erase codes and if they come back, have it scanned again.

EVAP codes should probably be repaired at a shop, since they can test each component with a high end scanner and isolate the problem.
