The ignition coils in my car are going bad. One right after the other. Mazda told me that the heat of the engine (miller cycle) is causing this. I think the engine was poorly designed. There are 6 coils & I have replaced 3 so far, 1 in 12/04 & 2 in 4/06 along with all the plugs. This problem started in 2002 when cylinder #4 was misfiring. Mazda replaced the spark plug. The coil in cylinder #4 was the first coil to go bad. The original plugs were champion. I was told these were the wrong plugs especially for this type of high performance engine. Mazda said to expect to replace the other 3 coils. & then what? do we start over again? my car only has 32,000 miles on it. Both catalytic converters have been replaced. I think Mazda should do something to correct the design of this engine to allow the coils more air.
The first failure occurred on 2/2001. There have been 4 more since that date. Dt.
