What's the firing order

Look up your firing order here.

If your plug firing order is not correct, the car will run sickly or not at all. Stuttering, spitting, backfiring and no-start can be caused by incorrect spark plug wire placement which results in an incorrect firing order. The firing sequence of your plus is determined by the distributor, but if the spark plug wires aren't in the right firing order the engine will not run correctly. It's easy to screw this up, but thankfully it is now just as easy to correct!

Use this firing order reference information to look up the firing order for your engine. Select the year, then the make of your car. You'll need to know what type of engine you have.
