Help please, plug reading wizards!

Zach, I was lazy earlier. Big surprise. But here's how "I" read plugs.

Get the engine warmed up fully. Go drive it around some and get some heat soak in it. Now, do this as close to your drive way parking spot as possible.

Give a wide open blast into high gear. Back out of the gas and kill the ignition at the same time. Be careful not to lock the steering wheel if it's a column ignition. lol

Coast into your driveway parking spot and THEN read the plugs. Otherwise, all you're doing is reading "what the car did last", which might be idling in the driveway and you'll always get a rich reading like that.

That's my method and it's worked well for me. I'm sure others will be along to blast me and disagree.
