Green Spark Plug
Has anyone ever have an issue like this? ngk tr55 with 14K miles on them. My car started running a little rough and was down on power. She had a "different" note when cruising and also when in the throttle. At idle the typical "lope" was a little off, but couldn't pinpoint my issue. I don't drive her much through the cold months and didn't really notice she was running rough until she started to miss a little bit on me. I started with the plugs and they were definitely my issue. Shes like a whole new car again. She just didn't sound right and at wot throttle, I could tell she was not firing on all cylinders. All 8 plugs looked this way. They were all opened up from the original gap of .045 to .047-.048. Check these out:

Typically, but you could be getting the plugs too hot and still getting green from it. Do you have a way to run fueling data?

I've been doing some reading and lean conditions can cause this along with running too hot of a plug. Going to pull the tr6 plugs after a couple 100 miles and see whats going on. Looks like I need to invest in a wideband.

Some more detail about your setup would help form the conversation here. I'm assuming by your handle that you're boosted. A TR55 would be awfully hot in a forced induction application.
