2000 toyota tacoma 4 x 4 V-6 engine light. Diagnostic says left bank running lean but that is it. It has an O2 sensor before and after the converter. What would give this code?

Can you get me the exact code? Clean the mass air flow sensor. If the resistor wires look fuzzy it will set a lean code.

I have cleaned the mass air flow sensor several times. What resistor wires are you talking about, and the code I believe was P0107. Lean 2 Bank 1.

How would I check the O2 sensors. It has one before and after the converter? Is there a tester for them. I do not want to buy a bunch of sensors that I really do not need. It is the 3.4 V-6. I will be accepting your answers no matter what you think. I just would like to know what you think I should try first.

The sensors can be check with a volt meter Ideally the need to be checked with a scope. I need to know if you have a California spec. truck it is different the the federal spec trucks. If you look at the sticker under the hood it should tell you. I can post some checks and tests then. Ideally if you could rent a scan tool that will let you monitor the data stream you could read the long and short fuel trim that would tell us allot.

Let me know.

The truck is not california emission spec. I do have access to a scan tool also so if you can send the checks that will help me out.
