first off i was mistaken, i do have obd 2 (that is why i have two o2 sensors, because of the clean air act) both of my sensors on on the drivers side pipe, the upstream sensor is just behind the exhaust manifold and the downstream sensor is about 2 feet behind that...no the o2 simulator never gave me prolbrems before, it is in place of the downstream simulator which is used to monitor backpressure (since i dont have a cat on, this is need) the upstream sensor is the one that controls air/fuel ratio, so if it is in fact an o2 prolbrem i would think it would be the upstream not the simulator, and i just replaced the upstream about 2 or 3 months ago
