(i) Install the intake air surge tank (See page ES-522).
10. INSPECT CO/HC
(a) Start the engine.
(b) Run the engine at 2500 rpm for approximately 180
seconds.
(c) Insert the CO/HC meter testing probe at least 40 cm
(1.3 ft.) into the tailpipe during idling.
(d) Check CO/HC concentration at idle and/or 2500
rpm.
HINT:
Check regulations and restrictions in your area
when performing 2 mode CO/HC concentration
testing (engine check at both idle speed and at 2500
rpm).
If the CO/HC concentration does not comply with
regulations, perform troubleshooting in the order
given below.
(1) Check air fuel ratio sensor and heated oxygen
sensor operation.
(2) See the table below for possible causes, and
then inspect and repair.
CO HC Problems Causes
Normal High Rough idle1. Faulty ignitions:
– Incorrect timing
– Fouled, shorted or improperly gapped plugs
2. Incorrect valve clearance
3. Leaks in intake and exhaust valves
4. Leaks in cylinders
Low HighRough idle
(fluctuating HC reading)1. Vacuum leaks:
– PCV hoses
– Intake manifold
– Throttle body
– Brake booster line
2. Lean mixture causing misfire
High HighRough idle
(black smoke from exhaust)1. Restricted air filter
2. Plugged PCV valve
3. Faulty SFI system:
– Faulty fuel pressure regulator
– Defective ECT sensor
– Defective MAF meter
–Faulty ECM
– Faulty injectors
– Faulty throttle position sensor
