ES 330 V6-3.3L (3MZ-FE) (2004)
1. Check the thread and insulator of the spark plug for damage.
If damaged, replace the spark plug.
d. Inspect the electrode gap.
1. Using a spark plug gauge, measure the electrode gap.
Maximum electrode gap of used spark plug: 1.3 mm (0.051 in.)
If the electrode gap is greater than maximum, replace the spark plug.
Electrode gap of 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/sq.cm, 85 psi)
Duration: 20 seconds or shorter
If there are traces of oil, remove it with gasoline before using the spark plug cleaner.
