"knock" at idle? 200 1983

Having a bit of trouble with my '83 245DL (B23F with Chrysler ignition). It runs and drives fine at speed - no unusual hesitation or anything, but at idle, it has an irregular "knocking" sound. Doesn't sound like detonation, but more of a "thunk" sound. I can't seem to tell where it's coming from...

Cap, rotor and plugs were changed ~8k miles ago with a kit from IPD (white cap). New battery three weeks ago. Due for an 3k mile oil change, but that's all. Oh, and 202k miles on the motor.

Only odd thing is that when I popped the hood one night to check it out, I could actually see the sparks inside the cap while it was running. Not sure if I should be seeing that or not...

Any ideas? Can't get a new cap and rotor immediately - will have to order them. Anything else to look for?
