Inspection and Adjustment

Idle speed*1 rpm
No-load*2 (in "N" position) - 650±50
Air conditioner: ON (in "N" position) - More than 700 rpm
Ignition timing - 15°±2° BTDC
*1: Feedback controlled and needs no adjustments
*2: Under the following conditions:
^ Air conditioner switch: OFF
^ Electric load: OFF (Lights, heater, tan & rear defogger)

MASS AIR FLOW SENSOR
Supply voltage V - Battery voltage (11 - 14)
Output voltage V - 1.0 - 1.7 at idle* (Approximately 2.1 at 2,500)
Mass air flow (Using CONSULT or GST) - gm/sec 3.0 - 5.0 at idle* (12.9 - 25.3 at 2,500 rpm*)
*: Engine is warmed up sufficiently and idling under no-load.
