Same old story here. Slight coolant leak, next interval will tell the tale on where this is heading.
Interesting that coolant went up and lead went down. O2 sensor changed 1k into this interval due to a lean condition code, all has been well since then. For all those that comment, notice the first 2 intervals below.
