Been pulling my hair out and being nickled and dimed by this Dumb car. Have replaced all sensors, maf sensor, throttle body and sensor, all plugs and wires, air filter, oil filter etc. The latest mechanic says that it is not reading the front oxygen sensor and thinks the ecm is bad. Any way this can be checked without going to the dealership to get bent over. Can these be sent out for repair or anything else that somebody has figured out. When I also reset I can disconnect the back o2 sensor and it throws a code right away, when the front is unplugged it does not throw a code and it should.
