In a previous post "RANDOM no spark / start 1993 Toyota Camry 2.2" I asked for help (and thought I solved) a random problem.
The car has an intermittent, no spark / start problem. Sometime it starts and runs with no problem, other times it will crank with no spark at all.

I've seen more than once when I use a spark tool to "see" if there's spark, it will change from no spark to full and the car will start right up.

I've tried wiggling wires, bench tested all components by the manual etc. etc.

I even stopped by the Toyota dealer for some insight and they agreed that the car must stay "broken" long enough to diagnose. Just a few minutes ago, I pushed it into the garage, put it on the lift and it started right up.

I have replaced the distributor/coil assembly (new unit), ignitor, ECM, charcoal canister and spark plugs to no avail.

ANY ideas would be greatly appreciated.

Did you try changing the plug wires with the plugs?

I didn't - this is not an engine miss problem. It's either all 4 firing with perfect performance or nothing.

My experience with wires is that you'll get a 1 or 2 cylinder miss, backfire, rough idle etc.
