How do you know when a coil pack is going bad on a

[hondajohnson]

pontiac sunfire? The check engine light has just came on. I checked it and it said misfire, so I tuned up the engine, and the computer is still saying misfire. So is the coil pack going bad? How can you tell because the car is still running good. It is just a little hard to start but it does start.

I gather you car is a bid older and has a few miles already on it? If I was you if that's the case I'd try cleaning the coil feed wire connectors and contacts but I think it's the coil and really you should go to a do it yourself auto wreckers that offers used parts cheap and pick 1 or 2 of those coils up.

Hope that helps and best of luck.......by the way my car showed that same kind of problem once and I changed the coil later another code said the coil wasn't performing to it's peak performance capabilities lol....So I changed it back and it worked fine now for ages lol
