3 months in storage, take it out since I go to the dealership on Sat on the lugnuts thing, and the check engine comes on. Never saw that before. The radiator fan inmediately turns on with a howl. I pull the engine cover, the electrical connection to the TB/MAF is unplugged, so I reconnect. The radiator fan stops turning on. My plan is to disconnect the neg post of the batt tomorrow, sit for about 10 minutes to clear itself then restart-basically a reboot. Funky smell too. Any other ideas? No codes shown so I assume just an unplugged connection fault and a stored memory.
