Hi all
Thinking of ways to keep the car running smoothly and was thinking of taking the sensor out of the header (1993 wrx saloon) and giving it a spray down with some brake cleaner. Is this worth doing or will it do nothing at all?
If i do it, should i reset the ecu?

Thanks all

Johnny

wont do much
the actual part that you would need to clean is inside the caseing i think

dnb

You'll probably do more harm than good. They're easy to break, especially when they're old and the threads have seized a bit.

If you want to clean it, go for a decent drive.
