Things I noticed on how my 88 S4 runs now...
Tank was near empty, filled it, dumped in can of seafoam..
SO...
I need to put a scope on it, but certainly sounds like a loud injector on the drivers side tickin away.
And at WOT, ya, its gotta small miss, and you feel tiny surges of MORE power in there somewhere, but you dont -get- it.
The beru wires are new, I have a new set of caps and rotors on the way as well.
Gotta test out temp sensors for proper output as well, and O2 sensor..blah blah blah...
And someone decided that thick brown gravy was to be used for power steering fluid.

They LOOK fine casually, and I just spent 5min in the dark..no fireflies.
But you want me to look under the coil wire coming off the coil itself?
I'll add that to the list in the AM

remove both of the coil wires if either end is corroded especially in the coil connection then you may have a leaking coil and they might need to be replaced, the caps should also be checked for cracks, Check the hall sensor connector behind and under the right cam tower and the knock sensor connectors

Slight miss on WOT acceleration, no fireflies, but associated with damp weather. Turned out to be microscopic perforation around base of one spark plug tower on PS dist cap, right at the edge of the plug wire cap. Couldn't see it without getting it super clean and using a 10X loupe. Fixed the problem. Was looking there because when both caps were clean, the brass electrode on that one cap connection was discolored, sort of gray, while all the others were shiny (what you see when you look down into the cap after removing a plug wire). Made me suspicious. The moral is simply that no fireflies doesn't mean no HT shorting...
