Dhodges Posted July 18, 2016 Report Share Posted July 18, 2016 I posted about misfire issue with my 08 edge, having ford post issue as a tsb and not a much deserved recall. My wife had our 08 edge towed to the local ford dealer in jasper ga "schottenkirk ford" with a horrible misfire and with the check engine light on. She was contacted by the service advisor being told that it had misfire codes for cylinders 1,2,3,4,& 5 and the bad coils "fried" the processor, cost to repair $3000.00. Being an ASE master certified technician with 25+ years experience i did not feel this could be possible since she shut off the engine immediatly upon drivability issue. The vehicle had approx 90,000 on spark plugs, ignition coils still original. Knowing fords inability to design a coil to last and knowing plugs were due for replacement i searched ebay and found 6 new aftermarket coils that have lifetime warranty for $100, motorcraft oe plugs and intake seals for $28. Upon removal of coils i could not find any visual trackings or burn marks, did find #5 spark plug cracked. I replaced all coils and plugs since i already had all. Checked for trouble codes and did not have any, drive cycle was complete, this seems odd with no codes and drive cycle complete on a vehicle that has a."fried" ecu. The vehicle is fixed, mo processor needed as schottenkirk ford had told my wife. As a ase master tech with 25+ years experience i can only figure 1 of 2 reasons my wife was told it would take $3000 to repair her edge, schottenkirk ford either 1) tried to take advantage of my wife or 2) neither the technician at schottenkirk ford nor the service advisor know how to properly diagnose and repair a vehicle.

DRbillZ Posted July 18, 2016 Report Share Posted July 18, 2016 My question is this. If you're a mechanic, why did she have the car towed to a dealer? Quote Link to comment Share on other sites More sharing options...
akirby Posted July 18, 2016 Report Share Posted July 18, 2016 Did you test the old coils? They could have been bad. I guess now the only way to find out is to wait and see if the pcm fries the new coils. It's possible they were bad. It's also possible they jumped on the most likely diagnosis without actually testing the coils. Hard to say at this point. Quote Link to comment Share on other sites More sharing options...
