I have a 2003 Dodge Caravan with a 3.3 flex fuel in it. A few weeks ago I noticed a misfire but no check engine light came on.... well it has gotten a lot worse. I chased the problem down to a coil pack dead in cylinder 5 only. I change the coil pack.. two weeks later the same misfire comes back this time each coil tests good and so do all the wires to the plugs. I bought brand new plugs and wires anyhow installed those and well installing the plugs saw that I had very weak spark at the actual Gap. Can anyone point me in the right direction here?

 

Still broke? Verify you're getting 12vdc at the coil connector. If that's good consider another coil.
