(b) Alternative inspection: (1) Quickly accelerate the engine to 4,000 rpm 5 times.
(2) Remove the spark plug.
(3) Visually check the spark plug.
(4) If the electrode is dry...OK.
(5) If the electrode is wet...Proceed to step (C).
(6) Reinstall the spark plug.
(c) Check the spark plug for any damage on its thread and insulator.
If there is damage, replace the spark plug. Recommended spark plug:
DENSO madeSK20R11
NGK madeIFR6A11
(d) Check the spark plug electrode gap.Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug. Correct electrode gap for new spark plug:
1.0 to 1.1 mm (0.039 to 0.043 in.)
(e) Clean the spark plugs.
If the electrode has traces of wet carbon, clean the electrode
with a spark plug cleaner then dry it. Air pressure: Blow 588 kPa (6 kgf/cm
2, 85 psi)
Duration: 20 seconds or less
HINT:
If there are traces of oil, remove it with gasoline before using the
spark plug cleaner.
3. INSPECT CAMSHAFT POSITION SENSOR
(a) Using an ohmmeter, measure the resistance between the terminals. RESISTANCE:
835 to 1,400  at cold
1,060 to 1,645 at hot
NOTICE:
ºColdº and ºHotº mean the temperature of the coils themselve\
