Hi, I am a first time poster and am hoping I can get some help with my sons 06 expedition. It is showing two codes one says ''A primary/secondary coil." The second code says "high temp intake manifold sensor" I have replaced a couple of cop's on my truck and the code read on them that I had a missfire on a specific cylinder, so can any of you guys shed some light on this? Sorry I dont have the code numbers but this was the description. Thanks

Chris
