Hey guys, Im new to the forums and recently purchased a 350z. The other night i replaced my air filter with a k&n cone filter, in the process i removed what i believe was the mass air flow sensor. When i started the car back up i had an engine management light :/ Ive tried ignoring it and hoping it would go out. Ive also tried disconnecting the battery fully and reconnecting after 15 mins. Im out of ideas and was hoping someone could offer any advice? Thanks
