I suppose at some time or another, the coil(s) are certainly going to need replacing. However, I've gone through the whole procedure of plugging in the code reader, seeing what cylinder is misfiring, interpreting the code to be a coil, and replacing it.
But now after about 10 thousand miles, the check engine light goes on again and it's the same code. The coil again. i know if I replace it, it will run just fine but I feel it indicates an additional problem elswhere. Anyone out there ever had that problem or know the reason for this?
