Do spark plugs have wires?

Spark plug wires (also called “ignition cables”) carry high voltage current from the ignition coil(s) to the spark plugs. On older engines with distributors, the wires run from the distributor cap to the plugs, and come in different lengths to reach the closest and furthest spark plugs.

How many spark plugs does a 2004 Chevy Cavalier have?

Usually an engine has one spark plug per cylinder, but some engines may have two spark plugs per cylinder.

How do you test a coil pack on a 2.2 Ecotec?

Touch the black wire of the multimeter to the center, negative terminal of the ignition coil. The resistance reading on the screen is for the secondary coil. If the reading is not between 10,000 to 11,000 ohms replace the ignition coil.

Can a car run without one spark plug wire?

Without the spark plug present, there is no way for the car can convert chemical energy present in fuel to heat for the car to drive. But if it is a multiple cylinder engine, then your car can still drive with a missing plug, however, this will cause instabilities to the crank.

Can you drive with bad spark plug wires?

Continuing to drive with worn out or damaged spark plugs can ultimately cause engine damage, so don’t put it off.

What happens if you switch spark plug wires?

When one or more spark plug wires are crossed, the engine may not run, or runs roughly as the timing of fuel/air compression does not align with the delivery of the spark.

Is it hard to change spark plug wires?

Luckily, replacing your spark plug wires is fairly easy and typically requires no tools. Start at one end of the engine and remove only the first spark plug wire by pulling on the boot at the end of the wire until it pops off. Follow the wire with your hand to the other end and remove it from the distributor cap.

Where are the spark plugs located on a 2005 Chevy Cavalier?

You have to remove the black piece in the center on top of the engine. This is your coil pack. Unbolt and disconnect it, pull it up. Underneath the coil pack you’ll see 4 spark plug boots that extend from it, down into the head.

What will happen if the spark plug gap is too wide?

The customer may experience loss of power, misfires, spark plug fouling, increased plug wear, or poor gas mileage. Too small of a gap may give too weak of a spark to complete the combustion process within the engine; too wide of a gap can lead to the spark plug not firing correctly, causing misfires at high speeds.
