NOTE: You'll need a dwell meter with a 90°scale.
- Run the engine to normal operating temperature.
- On the 2.6L engine, connect the dwell meter (+) positive lead to the yellow/green
wire in the check connector, located near the No.3 air control valve and reed
valve case assembly. Connect the (-) lead to ground.
- On the 2.2L engine, connect the dwell meter (+) positive lead to the brown/yellow
wire in the check connector, located near the No.3 air control valve and reed
valve case assembly. Connect the (-) lead to ground.
- With the engine at the normal idle speed, the dwell meter should read 27–45°for
the 2.6L engine, or 20–70°for the 2.2L engine.
- If not, check the oxygen sensor, the wiring between the oxygen sensor and
the feedback control unit, and the control unit itself. See Section 5 for
procedures. If all components check out satisfactorily, adjust the mixture
with the adjusting screw.
The idle mixture is controlled by the Electronic Control Unit (ECU) and is
not adjustable.
