Need help...misfiring problem

[cupeekn2]

Hi guys, long time member, first post. I just changed my plugs to the NGK iridiums, and gapped them to .025. The car was misfiring before I changed them, and is still misfiring after changing them all out. I have an OBD 2 reader, and it said that I had misfiring on cylinder 2 and 7. So, I pulled them both, checked gaps, checked the coils, everything looked really good, so re-installed. Car still misfired, this time only cyclinder 2. Sorry for my ignorance, but where is cylinder 2? Is it the 2nd one back from front bumper, on right hand side, when sitting behind the wheel? That is what I thought it was, and checked. Is it probably a bad coil, even though they all looked great? My car is a 2005 ctt with 24k miles.

Thanks for help in advance...

In driving direction: cyl. 1 - 2 - 3 - 4 = bank 1

cyl. 5 - 6 - 7 - 8 = bank 2

You have to change all the coils to be sure, they will cracked sooner or later.

Buy the original spark plugs, they are very good and without issues.

Thank you so much RFM! Is bank 1 on the right side when in the driving seat? Bank 2 on left?

Thanks again

Right side in driving direction is bank 1.
