So... Sunday evening, I removed the airbox and was looking for this pressure sensor along the lines. Found one under the airbox. 4.8iS model.
Anyway. There was one there. I unplugged it, sprayed some contact cleaner there and then I reconnected it.
Well, the AC hasn't done the random cut out since. That includes a trip across town and back yesterday as well as to and from work both days in this 100+ degree weather.
So I may indeed have a bad sensor.
Question is, is I unscrew it to change it. Will freon escape out into the atmosphere? Or is it safe to change out just like that.
