I would be making my own homemade smoke machine like the one’s made out of paint cans that’s seen on youtube. I would be using a pressure regulator so I don’t go over 2 psi.
Has anyone ever tryed it or know someone who has?
I’m doubting the gas cap is the problem. Giving it one more shot, cleaned the top of the filler neck with alcohol even though it wasn’t that bad, cleared the code and see what happens
