Engine Fuel System 
 
The fuel injection system is all-electronic and is microprocessor controlled. It can continually 
compensate for variations in engine load, speed and temperature to give the best economy and power. 
The most unique feature of the system is the air mass meter which measures the mass of the inducted air 
instead of the volume. In this way the system can make instantaneous adjustments for changes in air 
temperature or density, thus always assuring the best economy with the lowest possible exhaust 
emissions.

Special instructions for work on the fuel injection system 
Extreme cleanliness is essential when working on the injection system. Great care must be observed.  
Injection system service should be handled by qualified technicians, using equipment intended for this 
service. 
Fuel (line) filter 
We recommend that this filter be changed every 60,000 miles (96,000 km). The filter is replaces as one 
complete unit.  
Replace more frequently if contaminated fuel was introduced into the tank.
