Have a fuel smell when 4runner is parked, not while driving. It drives fine but the check engine light and traction control light and vsc traction control lights. I just put it in the shop just wondering if it's the EVAP system maybe? And if I should've reset the computer before putting it in the shop? My wife took it to Autozone they put a scan tool on it. They said it had codes, no specific codes, referring to some part of the fuel system.
