Maybe you ate something different for dinner last night....so not used to the new exhaust fumes...
but..last time when i was getting my hids and battery replaced, i accidently moved a few things around in the engine bay...and it came in contact with the engine block and it started heating up, and smelling..kinda like smouldering plastic..
