My 2004 Aveo sedan has developed a minor flooding problem. The car starts in the mornings and anytime after driving fine, with the exception of right after I add fuel, and I normally fill the tank. After filling, the car floods and takes about 30 seconds of turning over the starter without touching the gas pedal, for the car to start. Runs perfectly after that, no stumbling or stalls, stop and restarts fine until the next time I have to re-fuel. Any ideas? Thanks!
