OK, I'm a bonehead.

Quite a while ago I posted that my '94 945T was bogging badly under acceleration. I tested & inspected just about every fuel & electrical component under the hood and although I got marginal improvements, it never really went away. Since I wasn't driving the car (my daughter had it at college) I kind of forgot about it and she just lived with it.

Well, we've recently been commuting together and it was still doing it's trick so I decided to fix it or blow it up. Before I could start, she wanted to go to the store. It wouldn't start.

It was a cool rainy day. I think problem with the secondary manifesting with the dampness.

Sure enough, I see some nastiness on the coil tower. I remove & clean the coil with some WD-40 as well as squirt the HT lead (all wires are fairly new). Put it back together and it starts right up.

NO MORE BOGGING EITHER!

Don't know how I missed the dirty coil tower all this time. I was convinced it was something esoteric like the knock sensor or computer (I had already tried known good power stages, etc).

So remember to check the basic stuff. It might just be that simple.
