Hello my car is misfiring. I have done a diagnostic test to the car and it tells me that it is misfiring. I have already replaced the sparkplugs but the check engine light is still on. What else could be making the car misfire?

An engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
