Checking plugs
The first time was tricky but now it's at breeze. You will get the hang of it....
You will not change the read that much if any.
Tons of guys leave it running with an auto trans.
I've done it both ways and the plugs read fine.
Never had a fancy modern injected car so who knows??
Oh yea, maybe I'm just old, but I would NEVER touch the key going down the track.
Switch panel is different, key, never!!
