You have made some specific statements there that may apply to some specific cards but in my experience are not typical, and there some statements that are not accurate. The O2 sensor just measures the remaining Oxygen in the exhaust, and tells the ECU to add or remove fuel when it is in closed loop control mode. It only indicates to the ECU how the engine is burning fuel. Nothing else! | |

Running rich is dangerous to your catalytic converter. It will overheat. Its not a big deal during startup, but over a long trip (especially at high speed cruise) it could be an issue. As for $1700 for a CPU reset - complete rip-off. 1) resetting the CPU fixes nothing. 2) primary O2 sensor failures are detected right away. BTW, after 2 minutes, whether the car's sensor indicate its warm or not, the car must go out of 'warm-up' mode. That's a federal emissions requirement. | |
