Subaru XT sensor question. I have a 4 cylinder 1986 XT with the EA82 engine. I am having starting and smooth idle problems and noticed a sensor with partially exposed wire. But neither the Haynes, Chilton or Subaru manual describes what I am looking at. The sensor screws into the engine behind the intake manifold and adjacent to the drivers side about 1 inch of the throttle cable. There are two wires one red the other blue coming out of this cylindrical device. I suspect it is an oil sensor, but the regular oil pressure sensor is in the front of the engine as described. Also, if you know what this is - can it cause the engine to not start and/or idle roughly?
