The first codes I got were P0117 (Engine coolant temperature circuit low input) and P0140 (O2 sensor circuit no activity detected (bank 1 sensor 2)). That is when I replaced the coolant temperature sensor and the front O2 sensor on the exhaust manifold and reset the codes. When it continued to die, I got P0300 (random multiple cylinder misfire), P0140 (again) and P1133. Then I replaced the spark plugs and wires and reset the codes. Today, the service engine light was not on but I connected the tester again and got P0131 (O2 sensor circuit low voltage (bank 1 sensor 1)). After I ran it to test it again and see if other codes come up, the P0131 code cleared itself but it still sputters and dies after the engine is warm and no more codes have come up. When the engine is warm and dies, it will start and run rough with no power to move the car unless I turn it off and let it set for a few minutes. As the car cools down it will start and operate near normally for a several hundred feet and then sputter and die again. If it cools down completely I can get up to 2 miles before it looses power and dies. Did we replace the wrong O2 sensor? I do not think I have time to check for spark, because it will start but run rough if I try to start it right after it dies. I appreciate your help.
