Burnt Smell from vents, some smoke from engine bay.

So I noticed a burnt smell coming from my vents today, so i parked and popped the hood, I noticed some smoke coming from the back of the engine, below the throttle and cruise control cables. I havnt noticed any loss of power, or strange behavior, temp is normal. It isnt a lot of smoke but enough to smell from vents and to look closely at.

Almost at 190,000 kms.

Any ideas?
