(h) Install the 6 ignition coils.
Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf)
(i)
Install the intake air surge tank. (See page
FU-17
).
10. INSPECT CO/HC
(a) Start the engine.
(b) Run the engine at 2,500 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 2,500
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
2,500 rpm).
If the CO/HC concentration does not comply with
regulations, perform troubleshooting in the order
given below.
(1) Check A/F sensor and heated oxygen sensor
operation.
(2) See the table below for possible causes, and
then inspect and repair.
