Question about Mazda 626
Code 17 is telling you that computer is not seeing Oxygen sensor changing like it should indicating rich or lean engine running condion. Since you are saying smell like fuel, I would guess at too rich. Is your fuel pressure ok. Pressure should be 27-33 psi with vacuum applied to pressure regulator and 34-40 with no vacuum applied. Also disconnect the vacuum line at the pressure regulator with engine running and check to make sure no fuel is present. Older pressure regulator diaphrams will often rupture which will allow liquid gasoline to be drawn directly into the intake manifold via that vacuum line. This could cause stalling and code 17 as well.
