I am starting to hate my ford

 

What is your truck doing? Mine misses at low RPM's. I took it to the dealer and they put in new plugs and a new #4 coil wire. After 100 or so miles it started agian. Anybody got any ideas?

 

I had my #6 coil fail on my about 10k ago. I measured an infinite resistance on the secondary side of the coil. Before that I measured another and it was around 8000 ohms. They are supposed to be 5,500 ohms. I've been told they just start failing like that...one after another. At least the price on those things dropped by almost half.

 

How do you measure the resistance? Exactly where do I measure?
