1979 CHRYSLER LEBARON Manifold Temperature Sensor 318 Lean Burn motor. WOW what a piece of work on the sensor. I have a few different types for my Mopars but none are like the none that is in the car or the replacement. I appears there is a slot for a small screwdriver and your supposed to adjust it to the temp in the car. Who in the hell ever heard of anything like that. I know, not I.
