P351 Code
I keep having a misfire problem on my truck. Primarily form coil 1. I get OBD code 351 Ignition Coil 1 Primary/Secondary circuit fault. I have had the computer checked out by for service Department. I'm told it is working properly. I have replaced This coil 4 times now. First 3 time replaced by Napa Mileage Plus Coils. I kept replacing them under there warranty. I just yesterday spent the money and replaced it with a Motorcraft Coil. I was told by a Ford Mechanic that was my problem I wasn't using Motorcraft coils. 10 minutes after putting in new coil truck began to misfire. When it misfires it shuts down AC which is a problem here in Texas where temps are over a 100. I'm told the AC shutting down is normal and is being done by the computer when it detects the misfire. I also replaced the spark plug when put on new motorcraft coil and it was gapped to the correct gap
I had to replace the Ignition Coil connecter back in May. Could i have gotten a bad connecter?
Can someone please give me some advice on what to do or what you did if you had similar problem?
