Vacuum Switch B23F
By Superloop
1983 242 b23f lh2.1 w/ Chrysler ignition. Can someone tell me what this is? I cannot find a definitive answer. It definitely seems factory, but is capped. Best guess so far has been an unused over pressure or charge air overpressure switch as if my car was to be turbo’d but wasn’t. Could also be possible related to ignition or egr?
