Thanks for all of the advice. I cleared the codes this morning. The codes were 113 and 231. I drove the car all day and the light didn't come back on. Power and fuel economy appear to be normal. Also the idle is normal. The only thing I changed was the end of the vacuum hose on the fuel regulator. It was pretty lose, so shortened it a bit to get a good tight seal. So maybe the regulator was not getting full vacuum. I will read the 700 faq on diagnosis. After this experience I want to know more about the LH system.
It does have its original O2 sensor, but has a relatively new AMM installed at the dealer (by the previous owner). The stove pipe (preheater hose) disintegrated long ago so there us little risk of frying the AMM.
