Adjustment procedures
To ensure the best performance and economy of your engine, it needs to be tuned regularly. Although computerized engine management and the use of more durable engine components have reduced the need for ignition...

Spark plugs
The spark plugs ignite the air/fuel mixture in the cylinder when the piston reaches its maximum compression point. The controlled ignition causes the piston to move downwards, turning the crankshaft and the rest of the...

Removal spark plugs
CAUTION: Keep hands, clothing and tools away from the radiator fan. On some vehicles, the fans may turn on automatically for up to 15 minutes after the engine is turned off. 1. Number the wires so you don't mix them up...

Inspection of spark plugs
Check the spark plugs for deposits and wear. If you are not going to replace them, you need to clean the spark plugs thoroughly. This can be done with either very fine sandpaper or a small flat file. Do not use a wire...

Installing spark plugs
The 1990-91 Accord and Prelude use a new type of plug with a longer tip and shorter lead-in. When replacing these plugs, make sure the same (identical) type is used. Cars using this type of plug have small emblems on...

Spark plug connection wires
Check and replace At each adjustment, visually inspect the cables for carbon deposits, breaks, or damage to the insulation. Check the caps and nipples on the distributor cap and coil. Replace any damaged wires. Always...

Frequency of ignition
Firing timing is the order in which the sparks alternate between cylinders. The spark must occur at the correct time in the combustion cycle, otherwise engine damage can occur. For this reason, connecting the correct...

Electronic ignition — description and diagnostics
Description of the system All cars produced between 1984 and 1991 are equipped with an electronic ignition system. This system does not have contacts or a capacitor; it does not require periodic maintenance. The...

Checking and adjusting the magnetic resistance gap
1984-89 Accord and carbureted. 1984-90 Prelude. 1. Remove the distributor cap and rotor. 2. Turn the crankshaft so that the magnetic resistance marks are aligned with the ends of the stator. 3. Using non-metallic...

Checking the breaker module
ACCORD and PRELUDE 1984-89 with HITACHI distributor 1. Disconnect the wires from the breaker module. 2. Using a voltmeter, check the voltage between the blue wire and ground, and then between the black/yellow wire and...

Checking the breaker module input
Checking the breaker module input on ACCORD 1990-91 1. Remove the distributor cap, rotor and screen. 2. Label and disconnect the 4 wires from the breaker module. 3. Turn the ignition ON. Use a voltmeter to check for...

Checking the spark
The spark test is used to find out if the ignition system is sending current through the coil to the distributor. Use this test as a preliminary test if you crank the engine and it does not start. This is a simple test,...

Ignition Coil Test
All resistance values are given for a coil temperature of 21°C. Resistance will vary with temperature. Use common sense when interpreting the data. ACCORD 1984-85 and PRELUDE 1984-86 1. Number the wires and disconnect...

Replacement of ignition system parts
Replacing the distributor cap and rotor The distributor cap is secured to the housing with screws. With the ignition off, loosen or remove the screws and remove the cap. Inspect the inside of the cap for cracks...

Ignition timing — checking and adjustment
The ignition timing is the setting of the moment of spark supply in relation to the piston position, in degrees of crankshaft rotation angle. In an ideal situation, the air/fuel mixture is ignited and begins to expand...

Valve clearance — adjustment
As part of every major tune-up or service, the valve clearances should be checked and adjusted if necessary. For all Accords and Preludes covered in this book, it is recommended to do this every 25,000 km or every 12...

Adjusting the air-fuel mixture
This procedure is used to adjust the basic idle speed on carbureted engines after replacing or rebuilding the carburetor. The mixture ratio is normally set at the factory and should not be changed or adjusted...

Idle speed control
Carburetor engines On carburetor engines, the idle speed should be checked with the engine warmed up normally and the fast idle system not engaged. Connect an external tachometer or use the standard one on the...
