The computer is saying that it cannot adjust (adapt) beyond the lower limit. This means that the O2 sensors are detecting an extremely lean condition so there is either too much air getting in (air leaks), or too little fuel (bad fuel pump (pressure or flow) or clogged injectors, or the sensor (MAF) is broken. The MAF is the chief suspect in this lineup.
