The firing order is 1-8-7-3-6-5-4-2 and the #1 cylinder is located at the left front of the engine and the spark plug and ignition coil for the #1 cylinder will be the first ignition coil and spark plug on the front of the left side of the engine on top of the valve cover, and to remove an ignition coil dis-connect the wire connector to the ignition coil, then remove the bolt securing the ignition coil (usually this is one 10 mm bolt) and give the ignition coil a twist as you pull it straight up and out of the spark plug well, and if you are removing the spark plug then use a socket with an extension and swivel to loosen up and tighten the spark plug, but use about a 6 inch length of 3/8 inch fuel line pushed onto the spark plug to actually remove the old spark plug and also to start the new spark plug down inside of the spark plug well to reduce the possibility of cross-threading or damaging the threads for the spark plug. Here are some images to assist you and the ignition coil location image shows the right side of the engine for reference, with cylinders 2-4-6-8 and this was just the best image that I could find to make that diagram, however they are laid out the same on the left side of the engine 1-3-5-7, and let me know if you require any further assistance.

It fixed my herky-jerky & knocking sound.! I was getting a code p0303 misfire on cylinder 3 so I had the spark plugs but not the ignition coils (75.00 each). The problem still existed then I thought it was bad injectors had them cleaned. I had spent 250.00 with a mechanic on it already. So i spent the 75.00 on just that ignition coil at autozone and researched via this diagram what was the location of cylinder #3 and when I took it off the coil was burnt and the mechanic shouldve caught it. Replaced it and it runs back to normal. Thanks!!!!!
