INSPECTION
HINT:
This check is used only to determine whether or not the idle CO/
HC complies with regulations.
1. INITIAL CONDITIONS
(a) Engine coolant at normal operating temperature.
(b) Air cleaner installed.
(c) All pipes and hoses of air induction system connected.
(d) All accessories switched OFF.
(e) All vacuum lines properly connected.
HINT:
All vacuum hoses for EGR systems, etc. should be properly
connected.
(f) SFI system wiring connectors fully plugged.
(g) Ignition timing set correctly.
(h) Transmission in neutral position.
(i) CO/HC meter calibrated by hand.
2. START ENGINE
3. RACE ENGINE AT 2,500 RPM FOR APPROX. 180 SE-
CONDS
4. INSERT CO/HC METER TESTING PROBE AT LEAST
40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
5. IMMEDIATELY CHECK CO/HC CONCENTRATION AT
IDLE AND/OR 2,500 RPM
HINT:
When doing the 2 mode (2,500 rpm and idle) test, follow the
measurement order prescribed by the applicable local regula-
tions.
