So, I pulled the spark plugs today to check to see how the engine is running. After pulling all 6 spark plugs, I've noticed there is a white deposit caked onto the spark plugs. I doubt this is normal operation, if anything this should indicate that the engine is running a bit off? But other than this, The car runs and drives fine, even under WOT, no indication of any issue or running rough.
We replaced the catalytic converters this week as well, The cats have white deposits on them as well, not sure what this is but i definitely don't want it to happen again to these new cats.
