  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Welcome. Just letting you know that I've moved this topic into the first generation Genesis Sedan forum...

Maybe try getting gas from a different station, or a different gas grade, just to see if that makes any difference.

Did the Check Engine/Service Engine light come on?

Does this happen after every fillup? Or just once in a while?

Classic symptom of a failed Purge Valve. If you can suck air or blow through it, it's bad. $30 part, easy fix.
