i have a 93 f150 302 thats running rich constantly , also when i start it ,it revs right for about 5 second and dies, then as it warms up it idles fine but runs rich. any ideas??
how bad is it running rich is it enoungh to get the plugs wet could be your fuel fuel pressure regulator not returning any fuel. it just leting it go all through do a fuel pressure test.
