I had a similar problem on my '92T. It was totally cured (8 mos now) by cleaning, contact lubing and retightening the ground point on the head (towards front of car). Try this first, It is cheap, easy and cannot hurt. It may very well be the AMM, probably not the ECU. If you are really into it, I can tell you that you can check the difference between the ground potential of the ground pin on the AMM and the battery. Mine differed by ~1V and would 'reset' when the AMM would burn off after shut down. It took a bit of sleuthing to find it. The LH ECU indicated lean because it was connected to the same ground point which would float above 0V and would try to richen it up until it was out of range. All the time the o2 sesnor showed 0.8-0.9V. rich! When you are talking about a sensor which reads 0-1V, it does not take a large deviation to throw the whole system out of whack.
