How do I know which spark plug wire goes where?

How to Find Out Which Spark Plug Wire Goes to Which Cylinder

1. Obtain the firing order for your vehicle. You can find the firing order in your vehicle’s owner’s manual or in a repair manual for your specific vehicle.
2. Find the cylinder numbering.
3. Number the terminals on the distributor.
4. Route the No.

How do you wire up spark plug wires?

Here are basic steps on how to connect spark plug wires in the correct order:

1. Get the owner’s manual for your specific car.
2. Check for the distributor rotor rotation.
3. Locate the number 1 Firing Terminal.
4. Connect the number 1 Firing Terminal to the first Cylinder.
5. Connect all the spark plug wires.

Can you put spark plug wires on wrong?

If you put the wire for, say, spark plug 1 onto the top of spark plug 4, spark plug 4 is now going to fire at the wrong time. If it fires when the intake valve is open, it could set fire to the fuel-and-air mixture that’s waiting in the intake manifold and the throttle body.

What happens if you put spark plug on wrong?

Engine Missing Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.

Can the wrong spark plug damage the engine?

Broken electrodes If the electrodes are broken off or flattened, it is likely that the wrong spark plugs are installed. A spark plug that is too long can cause extensive damage to your engine while a short spark plug can cause poor gas mileage and spark plug fouling.

What happens if a spark plug gap is too big?

One of the key factors that makes a spark plug work well, or not, is the size of the gap between the electrodes. However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn’t run at all.

Is an engine misfire expensive to fix?

Engine Misfire Misfiring of a cylinder can happen for numerous reasons. Here are the most common causes and related costs of the misfire condition: Carbon or oil-fouled sparkplugs: $100 to $300 depending on cost of plugs and labor to replace.

How do I know if I have a misfire?

Symptoms Of A Misfire

1. Rough Idling. Engines that idle in a clunky or rough manner could be suffering from misfiring.
2. Sluggish Acceleration. Your car might have trouble reaching adequate speeds if your engine is misfiring.
3. Engine Sound Changes.
4. Black Exhaust.
5. Your “Check Engine” Light Might Illuminate.
