Evap- i had my fuel pump replaced since I;ve had the EVAP not ready changed the cannister and switch in the rear, cannister in the front.. I am spent, what else can I do.. I even installed an O2 simulator after the cat no luck... I have driven for miles on numerous ocassions.. I've had the 440 code (evap), 420 (cat), 140 O2's
