5-4 FUEL SYSTEM TESTING AND DIAGNOSIS
Most fuel system malfunctions occur when the fuel/air ratio of the mixture is not correct.
This is usually caused by clogged fuel filters, air passages, fuel passages, or by variations in
the fuel level.
To get the best possible performance from the throttle body, make sure that the fuel feed and
air feed passages are free so air and fuel can flow freely through them.
The procedure for inspecting the fuel system is described below.
Run all system tests with a full tank of fresh, clean fuel.
