[QUOTE="EricM, post: 1245184, member: 20286"] Not sure what your plugs and coil change interval looked like, but the PCM can get fried by running the plugs and coils for too long. A large plug gap makes the coils, and in turn, the coil drivers work harder. The coil drivers are in the PCM and can damage the PCM. I just did all the coils and plugs at 60K miles on my wife's Edge to prevent exactly what I described. It's a very common problem on the 3.5L engines. Fortunately Ford has a tune up kit with 6 new OEM Ford coils, six new OEM iridium plugs and intake manifold gaskets for only $142. Just one single coil is generally around $80 for Ford parts. It's quite the deal. [/QUOTE]
