Yes they are a cumulative count since the last time they were cleared. They is an option in the activations menu to clear the counts and reset them to 0. Granted those number on the 2 4 6 are higher than the 1 3 5 counts and could mean a future problem. But could also mean nothing. A vacuum leak, bad MAF or it could be a DIC. What are your short term and long term fuel trims the long term will be the multiplicative. Also what is the percentage of the deviation from calculated at both idle and at a steady 3000 rpms. Let the number level out before you accept the reading.
I will admit I am partial to BKR copper plugs as opposed to the iridium plugs. But that is probably due to the number of older cars I work on at work. Many of them have problems with iridium or platinum plugs.Good Luck, Bernie
