pre-cat Oxygen sensor output voltages - Alfa 2L JTS engines
Posted: 28 Mar 2014, 09:23
I have a borderline high CO (Carbon monoxide) level which can be caused by numerous factors such as simply an old air filter, or worst case... fuel injectors. Before I touch anything, I would like to compare Oxygen sensor output voltages with another JTS owner to establish whether my sensors are getting tired! Any contribution at some time will be appreciated.
