If these sensors fail, misfires can occur.Engine misfires can be caused by a list of faults, but there are a few suspects that occur more than others.

Old spark plugs can simply break and fail to produce a spark. A broken spark plug is a simple fix: just replace it.You’ll get a misfire on any cylinder that has one or both that’s bad, you can swap the suspect coil or spark plug with a cylinder that is not misfiring and see if the misfire travels to that cylinder. If it travels with the coil, it’s the coil, if it travels with the plug, it’s the plug.
