Changed my plugs today all looked ok, like this.
Except plug #2, passenger front. Looked like this.
According to all the pics I can find on the interwebs its ash deposit, sometimes caused by fuel additives or cheap gas. The threads were also quite oily. Since its only on that one plug I'm thinking something else is up. I have also had a tick for a looooong time, as in years. And I have a high idle. No codes, but the EVAP and O2 HTR MILS won't set.
Any thoughts?
