I'm trying to figure out what this sensor is on the drivers side manifold (LO3 engine), it has a black wire comming out of it. and the wire goes down towards the engine mount into a connector, and from where I don't know. I doubt it is the o2 sensor since it's not that high up. I even noticed a similar thing on a 85 Fiero (it had a purple wire). So it must be a common thing on a GM engine.
Any idea what it is? Thanks
