Step-by-Step Guide for Checking Your Firing Order:
Turn Off the Engine: Always work on a cool engine and disconnect the battery for safety.
Locate the Ignition Wires: Ensure they are connected correctly according to the firing order. They usually go from the distributor cap to each cylinder in the firing order sequence.
Check the Distributor Cap: Make sure the order matches 1-8-4-3-6-5-7-2. If they are mixed up, you’ll need to re-route the wires.
Double Check the Connections: After routing, check for any loose connections that could affect performance.
Reconnect Battery: Once everything looks good, reconnect the battery and start the engine.
Troubleshooting
If you notice any performance issues:
Make sure the ignition timing is set properly.
Check for any damaged wires or spark plugs.
Look for vacuum leaks that could affect engine performance.
