I had five coil packs fail over the course of a year. Thank goodness it was just one at a time. I found the bad one by removing the fuel injection connector on one cylinder at a time. If there is no spark as in no coil working then the gas isn't getting burned. So when the injector is disconnected on the bad coil cylinder the engine still runs rough. You know no change in the engines rough idle when the injector connector is disconnected on the bad coil cylinder.

I drove about 80 miles on five cylinders when the last one failed. The idle speed has to be kept up to prevent stalling and then engine seems to run well above 2500rpm. So I also did downshifting.

When I got home I realized I could have disconnected the injector. I had forgotten about this. At least then I would not have been putting unburned gas into the cylinder. Oh well. It is one tough engine even at 320k miles.

Peace,
