2004 dodge stratus 2.4L not passing emissions test why
Emission saying: 1. Catalyst…Not Ready 2. Oxygen Sensor… Not Ready I put 375 highway miles on the car, hopping this will pass it.
In the car there is no Code to see, when I take it to the auto parts store when they check it out and there is no check engine lights. (It keep Failing emission test.)
I changed the o2 sensor, new spark plugs and wires, new gas with treatments.
Please can someone help me.
I don’t know what to do?
I can’t keep pull over by the police department for expired tags.
Any ideas?
Please if you can help

It's failing because you cleared the computer. The car has to be driven through a very specific drive cycle That includes many different types of driving and vehicle temperatures for those monitors to reset. A` straight cruise at constant speed will not reset the monitors.
