Metal Taste
1 Answer
A leaking AC eveporator coil, which is located in the heater box alongside the heater core. If you were running the AC or the defroster, it may have allowed a faint oily mist to spray into passenger cabin and onto windshield via the defroster vent. Any AC shop can test AC system for leaks. An exhaust leak, fuel leak, or EVAP canister problem may also leave you with an odor in the passenger cabin, although I don't see that causing a metallic taste in your mouth.
