Here are opinions and answers from FAQ Farmers: * The firing order is the order in which your ignition system sends a spark to each of your cylinders. All of your cylinders do not do the same thing at the same time, one is igniting the fuel, one is compressing the fuel, one is exhausting, etc. Spark is only going to one cylinder at a time in rapid succession. They generally do not send spark to the cylinders in the order of 1-2-3-4 ... (etc., depending on how many cylinders your car is) because the engine would be rough because the firings would go left to right. So they balance it by doing something like 1-3-2-4 ... etc. All cars are different in this order depending on model. If you put the wires on the wrong way, you can change this order and cause the engine to stumble because it will ignite at the wrong times. It will run like CRAP! Sometimes it is cast right in the block of the engine in letters. Sometimes it is in the owners manual. It is usually in a shop mechanic book. You can also find your particular order online by make and model and year. * The firing order is the order in which your ignition system sends a spark to each cylinder. * http://autorepair.about.com/od/enginefiringorders1/
