I have a single coil pack that has a clicking sound comming from it. Replaced the plugs about two months ago with split fires. Durango runs great, no other problems. Should the coil pack be replaced??? Or should all be replaced??? This could get expensive!

Thanks,

Just do the bad one. Sounds like it has a short. The others are fine.

 

I would replace the one thats bad. If it's arcing it may cause other electrical interference problems.

 

Thanks Guys
