Back on topic...
I used my 80 to pick up lumber to build shelves in my garage.
And today I got some goodies in the mail. Time to replace the 23 year old O2 sensors and eliminate the EGR.

Got a call that all of my parts are in at Toyota to do my tune up. New plugs, wires, cap, PCV valve, and everything else @jonheld recommended. Going to be a busy week for my girl.
I'm guessing I will increase my MPG from the 6 mpg that I am getting now to hopefully 12 mpg. I will pee myself if I do.
Mine has all of the above + no AIR pump. Had the engine completely rebuilt & now I'm getting 11ish mpgs.
It's possible!! Took 2 years though
