have been driving a 94 and 96 nissan sentra for several years. THE
96 CONSISTENTLY AVERAGES OVER 4 MPG GREATER THAT THE 94.
both are stock cars, 4 door, 1.6 liter engines, 4 speed/overdrive auto
transmissions, have same brand & size tires and use the same tire
pressures, which are adjusted monthly. both cars have almost identical
total mileage. no dragging brakes.
the 96 has a different shaped body and is presumably more
aerodynamically
efficient. however, both autos are driven in the same city & highway
mileage
conditions. the 96 gets better mileage in city driving, than does the
94.
is there some sensor, that DOES NOT set a computer code, that can
cause
the computer to run the 94 engine richer than the 96 engine?
