If you’re willing to go out of state, try Micah who owns Reliance Motor Works in Buena Vista, CO. He’s a Toyota trained mechanic and has been working on my domestic Toyota vans from the 1980’s, and my JDM Toyota vans from the 1990’s that have no tech manuals in English. He knows his way around Toyotas. He has been my mechanic for 13 years starting when he had his first shop in Corrales, and I still take my vehicles to him for serious work even after he moved to Colorado. DON’T go to Super 6 Tokyo in Albuquerque. Owner is also a Toyota trained mechanic, but is a rip-off.
Thanks for that suggestion. I do know Micah, I wish he was closer. I would have to tow the 80 up there to him and I would prefer to find help closer if there is an option.
Wow. You have spent a tremendous amount of time and energy on this issue. Here are a couple of general suggestions. These saved my butt many times over the years:
-Get a good leak-down tester. IMHO, one of these should be found in every toolbox alongside a quality voltmeter and a good timing light.
-Install an independent wide band oxygen sensor for air fuel ratio numbers. This allows you to diagnose the problem as either a sensor electrical ECU or an engine setup mechanical issue.
I will PM you the name and location of the shop in Albuquerque I go to when I need help.
If this shop isn't a super secret deal, pls post up here as others may need similar support with the same exact lean codes. These codes require someone who understands some serious voodoo magic! Interpreting O2 sensor voltage, combined with MAF sensor readings is seriously complicated. I have a lean code as well but i'm hoping to figure out when spring comes.

Serious voodoo magic? Nah! Toyota designed the vehicles, designed and made all the many thousands of parts required, assembled all the parts producing the vehicles, and they work as designed. Toyota does the assembly of these parts many thousands of times a day and gets the same results. Sounds like good science, great engineering, and quality production. Start with the science: Fuel, air, and spark. Chemistry?
