Can someone? I do not know if I can or how to do it. Or should I just repost?

Likely a different PCM. Those coils are on lots of models, but not all have the fried PCM issues.

Did your PCM have any issues from driving with bad coils? This issue definitely messes up the PCM in the Edge.

Ok, thanks for the info fish! In my mind, a fully failed coil is more likely to damage a PCM than a bad PCM damage a good coil. When you send the PCM in for repair CircuitBoardMedics has a repair form that asks if you replaced coils. If you have, it asks if you ran the car with a possibly fried PCM and the new coils on it, explaining it can damage new coils and they won't warranty the fix. I cannot find any surefire way to test a coil, as resistance doesn't seem to be a good determination. My fully melted coil tested fine resistance wise, but its far from fine.

My 2007 Edge has recently run into the dreaded melted coil/fried PCM issue. I replaced all coils and plugs and sent the PCM in to be fixed by circuit board medics.com. I guess what I am looking for is whether or not there is an updated PCM to correct the issue of failure when a coil fails, or if you just have to stay on top of your plugs and coils once the issue is remedied? Also, After replacing the coils and plugs I ran the car for a few minutes to check if PCM was bad for sure (it still misfired, so I turned it off after a few minutes). What is the likely hood the coils got messed up again? I have read an open driver current on the PCM circuit CAN melt them again, but all of them are perfect looking still.
