OK... so i'll try to keep this informative but short.

I have almost always had misfiring issues in REALLY wet road conditions or after i go through and automatic car wash. I changed the plugs, wires, cap many times and it never fixed it so i just thought it was how my [censored] was going to be.

Then one day browsing around the internet i find that MkIIIs have/had an ignition coil problem. The symptoms sound exactly like my issues.

So i got new coil, Bosch plugs, Bosch wires, Bosch cap, and Bosch rotor. I installed them on Thursday. My car ran better than before.... which i expected.

Fast forward... about 140miles driving and until today [Sunday]. We hop in the car and head to Seattle for something to do. Everything with the car is fine. We park somewhere for about 10 minutes come out, the car is running super rough and even died once while reversing out of a parking spot. AND NOW any time i put my foot into the peddle to accelerate it misfires like its nobodies business. It hasn't rained.... i didn't drive through any deep puddles or probably no puddles at all...

Even when i did have the rainy freeway issue it never lasted this long or this bad. Also my fresh oil change wreaks of petrol. Which im sure is from the misfiring.

What else should i check? Unfortunately i don't have any tools with me. They are about 60 miles north at my brothers house where i do all my car work at.

I have looked for water/moisture in around the cap, plugs, coil. I pushed on all the wires to make sure they were seated.

The only thing i can think of is my o2 sensor is completely shot and im just running in open loop so my injectors are flooding out.

I do have a new o2 sensor i just didnt get time to install it.

For what its worth, I had a friend with a VW Golf with the same problem and the cause turned out to be a leak in a cracked windshield.
 
This happened to my 96 Z24 one time when a friend who borrowed it was trying to be nice and washed the car then opened the hood and washed my engine. lol. Turned out it was the 2 coil packs. It kind of kept having the problem for awhile until I replaced them again with another new set.

As for some other ideas, I know a bad or clogged EGR with a poor functioning plunger can cause very poor idling and stalling. Worth a check as they aren't too hard too pull off on most cars and clean. Depress the plunger and make sure it goes up and down easily.
 
BAM!

i went out since its dark to see if i could see any electrical [censored] shorting out. Sure enough BRAND NEW plug wire cracked right before the plug boot.
