Question about 1990 Jaguar XJ6
I would change the air filter and clean the fine mesh covering the air flow control unit.
Make sure the connections are good as the sensor screen is tied to the O2 sensor. A new O2 sensor and dirty screen would give you poor fuel burning as the air fuel mix would be bad, and the O2 sensor would read the need for more fuel.......poor economy and running rough as it would not be clean burning.
