On the 93.5, there is only 1 O2 sensor. I know that 95 and above have a second sensor on the the catalytic converter. boing82 said that 94 have a second sensor as well.
So, if I have only one sensor, will the check engine light still come? It hasn't.
If it is not the O2 sensor that is bad and causing my catalytic converter to go bad.
Does anyone have any ideas as to what elso could be going bad?
A local mechanic wants to charge me $70 to run a diagnostic on the car. I would like to avoid this and hopefully do it myself.
Thanks again.
