This is a pic of one of my plugs. I haven't been driving the car, just running it on jack stands through my drivetrain and everything. I don't just let it sit and idle the whole time, I usually hold it up around 1500 to keep the oil moving good.
This plug looks different on each side, one side leads me to believe it is lean, the other looks correct.
What do you guys think about this?
Is it pointless to try and read plugs when the car isn't being driven?
