Ummm . . . . . Not sure where you got this information but it is wrong!!
If you read my statement I clearly said Aerosol spray type.
And it is very flammable!!!
Mabe you are thinking of the type that comes in the industrial size barrel or 5 gal. can.
If you look on an aerosol can it sez FLAMMABLE!!!!!
I also never suggested that anyone spray it into or on a modern day computer controlled carb. or Throttle Body....
But I did suggest that he may have some type of oil on his sensors as this seems to have been what caused my similar stalling issue.
after I installed a Spectre filter like the K@N type.
I never suggested he spray WD-40 into his X-Fire.
