I went to advanced parts and they checked my car
with a code reader. It says I have 4 o2 senors bad in the exhaust piping.My question is why all four? is there a way to check them out with an ohm meter to find the one that are bad?

first, i would take it to another place have htem scan it and tell you what the codes mean

if its bank 1 and bank 2 lean then the first 2 sensors are bad.

the last sensor on each side tells you if the catalytic converter is bad.
