Hello all,
I need some help with my Z. I did a oil change today and decided to change my spark plugs with some Iridium IX spark plugs. I carefully gapped three spark plugs (passenger side) and replace 3 out of 6 spark plugs. I started my Z expecting a smooth run and nope. I now have a check engine light and rough acceleration. Just as I feared I think I have a random misfire. I need advice to resolve this issue any is appreciated.

Thanks

sounds like you might have a bad coil pack....

Why would you not replace all 6 spark plugs?

Were the problems there before you did your maintenance? Did you make sure you plugged in all of the coils good and plugged the wires in correctly?

Oil on your spark plugs? I have a misfire but it's due to bad seals on my valve cover.

It got too dark to see and I didn't want to end my night screw hunting.

Thanks for the response Spike100

No, there wasn't any problems before the spark plug change. Yes I did check and later double check if the seating of the coil pack was securely on the spark plug .When I removed spark plugs there was a little oil around the rim of the plug but none on or between the electrode.

Thanks for the reply WeightLimit.
