check O2 sensor for excessive wear! Ideally, use a safe anti-seize compound on the oxygen sensor, or none at all. The O2 sensor also failed during warm-up, despite the instructions stating "do not leave the sensor in the gas stream without power to the heater”, it is strongly recommended to wait for the condensate to burn off before turning on the sensor , to prevent overheating of the sensor shock. ceramic element. Not sure if it was antiseptic or exhaust condensation as heating up too rich caused the sensor to fail after about 5 minutes. I plan to run the time delay relay control until the engine is warm and then run the sensor to avoid thermal shock.
