I have a 2002 two doors mercury cougar V6 1.5 liter automatic. It was miss fire on cylinder 4 and 5, but now it is miss fireing in all the cylinders randomly. But I can still drive it. The Check engine light is on, and it will not pass smog. I don't know what the problem is. I need need. Can someone give me the answer right away.
