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.

I just purchased a 2010 Genesis Grand Touring Coup with 3.8L. The guy said it needed a new motor but it runs. It threw 2 codes with the check engine light on. First code, system to lean idle bank 1. Second code, system to lean idle bank 2. There’s no knock or tick. It sounds good. Also the brake pedal is soft. The guy said the Brembo brakes had been bled with no air in the lines. Plz help! I’m not sure where to even start with this car.
