Thank you Alan this is exactly the sort of information I have been looking for mmm

Just had a bad coil, asked my mechanic if I should just replace them all he said no because they were expensive. 115$ each. But replaced all the spark plugs and bad coil.

He told you no because he would get to charge you the full repair cost each time they fail (more $$$), while in reality, if one fails, the others aren't far behind.
