IDLE SPEED/IGNITION TIMING/IDLE MIXTURE RATIO INSPECTION
EF & EC-29flowchartFor non-catalyzer model with CO-meter. M/T idle speed 850±50 rpm; A/T idle speed 850±50 rpm in N position. Ignition timing 15°±2° B.T.D.C.
NOTE
For non-catalyzer model [With "CO"-meter]
IDLE SPEED/IGNITION TIMING/IDLE MIXTURE RATIO INSPECTION — Non-catalyzer model with CO-meter
1
INSPECTION START
2
Confirm that engine is at normal operating temperature.
3
Check and adjust idle speed and ignition timing.
Idle speed: rpm M/T 850±50
A/T 850±50 (in "N" position)
Ignition timing: 15°±2° B.T.D.C.
Refer to page EF & EC-22.
4
Race engine (2,000 - 3,000 rpm) 2 or 3 times under no-load, then run engine at idle speed.
5
Check "CO" with "CO"-meter.
Idle "CO"%:
2.0 or lower
O.K.
return to step 10
N.G.
6
Turn off engine and remove air flow meter from vehicle.
7
Drill a hole in seal plug which seals air flow meter variable resister and remove seal plug.
8
Install air flow meter on vehicle. Start engine and warm it up untill water temperature indicator points to the middle of gauge.
9
Adjust "CO"% by turning variable resistor on air flow meter.
Idle "CO"%:
2.0 or lower
10
Race engine two or three times under no-load, then run engine at idle speed.
11
Check idle speed.
Idle speed: rpm M/T 850±50
A/T 850±50 (in "N" position)
N.G.
