It is interesting that the temp 1 sensor is not listed as the possible
culprit in any of the troubleshooting tables.  But as discussed by others on
the air temp issue, my spider takes in about 2 liters of air each cycle.
That air contains some weight of oxygen.  The injectors add the maximum
amount of gasoline, containing carbon, that the weight of oxygen can burn.
Since cold air has more pounds of oxygen per 2 liters volume, you can burn
more gasoline (and do more work) per revolution if the air is cold.  Or you
can add a turbo or super charger to compress the air and give you more
oxygen per revolution which can then burn more gasoline per revolution.  So
in the L-Jetronic, Bosche measures air volume and temp to estimate gasoline
need.  In the LH-Jetronic system, an air mass sensor is used, avoiding the
measuring problem but not changing the physics of a naturally aspirated
engine.
