Sorry, but I think using  WD40 to hunt for vacuum leaks is a VERY bad idea.
If I'm not mistaken, the oil in WD40 is a SILICONE.  SILICONEs contaimnate
OXS sensors.  That's why we are now being warned not to use silicone
sealants when installing OXS sensors.  Well, maybe if you want a reason to
replace your OXS, it isn't such a bad idea. :-)

BTW, read the label on your can of WD40.  The propellant is PROPANE!!!  I
know of one source of professional auto repair info that has the mechanic
search for vacuum leaks with an unlit propane torch.

Happy motoring!
