Car Idle and Ignition System

Could someone tell me if my car idle sounds as it should. Still a noob at detecting if my car has issues from the sound it puts out.

I changed my spark plugs as can be seen here...

ENGINE FRONT (facing car) - LEFT, MIDDLE, RIGHT

ENGINE REAR (facing car) - LEFT, MIDDLE, RIGHT

ENGINE REAR (facing car) - LEFT, MIDDLE, RIGHT

Anyone know why my REAR LEFT spark plug looks like that? Also, based on the Haynes manual, my plugs being white at the tips means that they are running hot. My coolant level is low but not enough for the thermostat to increase passed the center point.

Anyone know what this brown stuff on the coil pack insulation is?

Looks like it could BA dried dielectric grease.

Plug tips look perfect.
Don't worry about the brown stuff.
Sounds like a normal VQ to me.

Other than someone replaced 4 of the 6 spark plugs at one time, the engine sounds good. The rear left plug and rear middle plug are different from the other 4. But I see in the one photo a brand new plug on the right side, so I'm assuming you changed the plugs. So the old plugs don't matter any more.

The rear left plug (as indicated above) had oil on the threads, from a previous oil leak I assume. The leak has been fixed a long time ago and the tips didn't have the leak so I assume it was burnt off.

Honestly sounds fine. Watched the video twice. Brown studs is just gunk from people old. Change your plugs again maybe use some injector cleaner or seafoam honestly best bet
