Description and operation
A
spark plug is a device used for delivering electric current from an
ignition system to the combustion chamber of a spark-ignition engine to
ignite the compressed fuel/air mixture therein by means of an electric
spark while containing combustion pressure within the engine. A spark
plug has a metal threaded shell, electrically isolated from a central
electrode by a porcelain insulator.
Repair procedures
| 1. | Accelerate the engine to about 3,000 rpm for over 3 minutes. |
| 3. | Check the spark plug visually. If the electrode is dry, the spark plug is normal. If the electrode is wet, check the damage and electrode gap as below. |
| 1. | Check the spark plug for any damage on its thread and insulator. If there is damage, replace the spark plug. |
| 2. | Check the electrode. Measure the insulation resistance with an ohmmeter. If the resistance is less than the specified value, adjust the electrode gap.
Specification: 10 MΩ or more |
 |
| 3. | Check the spark plug electrode gap. If the gap is greater than the maximum, replace the spark plug.
Specification: 0.7 - 0.8 mm (0.028 - 0.031 in.) |
| •
| When adjusting the gap of a new spark plug, bend only the base of the ground electrode. Do not touch the tip. Never attempt to adjust the gap on a used plug. |
|
 |
The
combustion may temporarily become unstable due to the aged fuel and the
carbon deposits accumulated on the spark plug(s) after long-term
storage.
| 1. | Start the engine and keep the engine running at idle for 2 minutes. |
| 2. | Step
on the accelerator pedal and hold it steady at 4500 rpm with the shift
lever in N position to warm up the engine until the temperature of
the engine coolant reaches 80°C. |
| 3. | Keep the engine running at 2500 - 3000 rpm in the N position for 15 minutes.
 |
| •
| The 2nd method should be performed only if the 1st method fails. (The misfire-related codes recur.) |
|
| 1. | Start the engine and keep the engine running at idle for 2 minutes. |
| 2. | Drive the vehicle for over 20 minutes, keeping the engine speed above 3500 rpm. | •
| If equipped with manual transaxle, shift the gear properly for keeping the engine speed above 3500 rpm. |
|
 |
| 1. | Remove the ignition coil.
(Refer to Ignition System - "Ignition Coil")
|
| 2. | Using a spark plug wrench, remove the spark plug (A).
Tightening torque:
14.7 - 24.5 N·m (1.5 - 2.5 kgf·m, 10.8 - 18.0 Ib·ft) |
| •
| Be sure that no contaminants enter the spark plug holes. |
|
 |
| 1. | Install in the reverse order of removal. |

Other information:
Never move the shift lever from P
(Park) or N (Neutral) to any other position
with the accelerator pedal depressed.
Never move the shift lever into P
(Park) when the vehicle is in motion.
