Saw a YouTube video last Fall, regarding spraying the intake air side of an automotive dry air filter with WD40 to increase the filter's efficiency.
I tried it, and, after a few weeks, got an OBD II P0101 code. Cleared the code several times, but it always came back within minutes of driving. One possible cause is contamination of the MAF sensor. I ran half a spray can through yesterday, and then cleared the code. So far so good.
I don't think I'll try this again.
Has anyone else tried this, and did you have a similar experience?
