when i was messin w/my o2 sensor i noticed there was some oil in where it connects to the harness. wonder how i go about in cleanin it up. thinkin thats y i have cel 1.

 

up.

 

contact cleaner spray

 

Berrymans brake cleaner. I use it for cleaning out my RC motors it will not do any damage. Don't use carb cleaner,

 

hmm. dont people say carb n brake r the same? i used carb. wonder if it did ne harm?

 

Pull out the o2 sensor and let is soak a little in simple green then get some cue tips and clean it out followed by the air compressor air blower attachment

Should clean it all up allow to completely dry

Should be good to go?
