recently my check engine soon light came on. so i took it autozone and had it read. they told me it said that the second cylinder was misfiring twice and the person told me it also said spark plug. i checked the spark plugs but all look alright. i have bosch 4 platinum.

Hi there,

You cant see if a plug is faulty, what you need to do is get the ignition system checked on an oscilloscope this will give you all the information on the condition of the ignition system, start here.
