I Engine Mechanical Components
Torque manifold bolts
The manifold bolts should be torqued at the 600 mile inspection. A loose manifold could alter air/fuel
ratio and cause an increase in emission and/or poor driveability.
Valves
The valve clearance should be checked every 30,000 miles.
Vacuum fittings, hoses and connections
Unstable idle, misfiring or poor emission control is often caused by leaking vacuum hoses or
connections. Check hoses and connections on distributor vacuum unit, EGR valve and connections
heater control servo systems and hydraulic brake servo.

II Engine Fuel System
CI system
The B27F engine is provided with a fuel injection system called the CI system (Continuous Injection),
which means that the fuel injectors are open and inject fuel as long as the engine is operating.
This system has few moving parts, is reliable and meets the exhaust emission standards at maximum
efficiency.
Air supplied to the engine is continuously measured and determines the amount of fuel injected.
The air flow is regulated by two throttle valves.
The air flow sensor and the fuel distributor are integrally built as a single unit. A lever is actuated by the
air flow to produce continuous fuel distribution.
Fuel
91 octane RON (Research Octane Number). Unleaded fuel permitted for all models and required for
certain models (with catalytic converter).
A label on the instrument panel and on the rear fender, near the filler inlet, will remind of this
requirement.
It is unlawful to dispense leaded fuel into a vehicle labeled "unleaded gasoline only".
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.
