I do have the meter and it states P-0133. I did look it up, but it really doesn't tell me what to replace to correct the problem. I sold the car an I'm trying to get it to pass CA. smog, so I really don't want to go out and buy a service manual for it. Could be of some help? Thank you in advance.

A code P0133 may mean that one or more of the following has happened:

The oxygen sensor is faulty
The wiring to the sensor is broken / frayed
There is an exhaust leak
Possible SolutionsThe simplest thing to do is to reset the code and see if it comes back.

If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:

Check and fix any exhaust leaks
Check for wiring problems (shorted, frayed wires)
Check the frequency and amplitude of the oxygen sensor (advanced)
Check for a deteriorating / contaminated oxygen sensor, replace if necessary
Check for inlet air leaks
Check the MAF sensor for proper operation
