Could you please describe the electronic gremlins in more detail?

I forgot to mention the car's mileage, 240k miles. Owner isn't sure if the transmission is original or a replacement.

comment Can I use the same AFR sensor on both banks (bank 1 sensor 1 and bank 2 sensor 1)
I can imagine that was fun to hunt down :)

comment Do I have a bad ignition coil? Measurements inside
Since Cyls 7 & 8 are next to each other in the firing order I swapped the new coil on #7 with the one on #5. No discernible change in the misfire signature - I'm now suspecting a partially-clogged injector

I bought another coil and replaced both #7 and #8. It's still not firing smoothly, so something is still amiss.

comment Random Misfiring - Tried All Basic Fixes - Tech Says Engine Ground
How's your vacuum line? Is the rubber hose perished/cracked? The idle-hunting and hissing symptoms definitely make it sound like you have a vacuum leak.

comment What are possible causes for belt tensioner “chatter” at idle?
I can definitely sense that something is amiss with the throttle so the vacuum leak suggestion sounds like a good lead. It's like the throttle plate doesn't want to open as easily as it used to.

I wish I could embed videos in the question itself.

AFR woes can be deceptive. If you're getting codes for both banks all of a sudden,b I'm inclined to believe that the issue lies elsewhere.
