Ive got a few o2 sensors from the wreckers, they are a bit dirty but better than mine, can i use degreaser or carby cleaner to spray the sensor clean to hopefully work better, or will that stuff the sensor up? Cheers in advance
Cleaning the sensor does nothing at all, Best to replace them with brand new ones, I thought about cleaning mine but really you cant
I hear O2 sensors can be contaminated easily, I wouldn't recommend trying to clean it. just save up a bit, buy a new one and not have to worry about it for a couple years at least.
If you clean them you will stuff them. Replace with new as the responce time slows down when they get old.
