o2 simulators for drive clean??
I have to go for an etest soon however my post cat o2 sensors are disconnected since the threads on one of the manifolds came out with one of the sensors after trying to replace them.. After that i just tied them up and kept the o2 sensors disconnected since they have nothing to do with fuel trim. Now with these new obd etests I will not be able to pass! I cant even put the o2 sensor back unless i weld in a new bung since I welded the hole shut after the threads were ruined. My question is that if I were to buy o2 simulators, would it allow my car to pass? Or would the new systems detect some sort of modification.
