Q: Need to replace bad spark plug & coil pack on Ford Expedition but not sure what else I need besides the plug and coil pack?

asked by on May 21, 2017

I need to replace a bad spark plug/coil pack on my Expedition as it is misfiring and I'm hoping to purchase the parts online but I'm unsure what other parts I need besides the spark plug and the coil pack? I figured I would ask someone on here so that hopefully I only have to place one order online for everything instead of finding out later this week that I should have ordered more replacement parts besides the plug/coil. This is the first vehicle I've owned that has the coil packs instead of plug wires so I'm not at all familiar with everything required to do the job but my truck broke down last week and as a single mother of 3 I really need to get the parts ordered so I can find a mechanic to do the work asap. Thanks!!
