Hey brother, Hows it going. Well from what I gather some of the causes are, clogged injectors, low fule pressure ect. Here is a link that covers diegnosing lean o2 sensor's. Its pretty in depth http://www.asashop.org/autoinc/MARCH/TECH2TCH.HTM . It might help. But if all else fails just call the wizard Cory.

Restricted injectors are one.

Fuel pressure you can discount as fuel pressure affects the entire engine and you have only the left side running lean.

Vacuum leaks are another reason for lean exhaust.

But, rather than guessing a bunch of stuff, the best bet for you is to pull the actual codes, then diagnose and repair the engine per the FSM.

I'm not very good at reading some of the texting shorthand you use, but if you're saying that your Wife and your two unborns died, I am so very sorry for your tragic loss.

Bring your car down to L.A. and I'll be glad to take a look at it at my shop and try to help with some diagnosis.
