2. Disconnect the spark plug tips. When doing this, pull the tip, not the wire.
3. Disconnect the high-tension wires from the ignition coils. Before disconnecting, mark the wires so that you can connect them in the correct order later. The order of connecting the wires to the coils is also indicated on the wires themselves, if they are original spare parts.
4. Measure the resistance of the high-voltage wires with an ohmmeter. The nominal resistance value, depending on the length of the wire, is 3-20 kOhm (see illustration).
3.4 Measure the resistance of the high-voltage wires with an ohmmeter. The nominal resistance value, depending on the length of the wire, is 3-20 kOhm
If the resistance is too high, clean the wire contacts and repeat the measurement. Replace the wires if necessary.
5. Check the condition of the high-voltage wire insulation by bending the wire near the tip at a small radius. Make sure that the insulation does not have cracks. Otherwise, replace the spark plug wires with new ones.

6. Connect the wire tips to the spark plugs, following the markings, in the firing sequence of cylinders 1-3-4-2. Cylinder No.1 is located on the flywheel side.
