emissions test with this vehicle in cali ...not a good day .
possible the vapor control valve is defective .. the vapor system sucks vapors from canister .. this type setup I had problems with as it sucked liquid gas into the manifold thru this control valve.. so check that the gas is not getting thru this into the hose into the intake ..make sure the air cleaner air temp control is working need 110F air temp in the air cleaner housing .

post the cali emission report .. good luck .
