Check your oil level, replace the oil filter, replace the pressure switch and if the problem persists (which I doubt it will), you may have a pump problem, as Josh mentioned.
If you're loosing oil pressure (I'm thinking of your other thread here), check all over the block and check all your lines for leaking oil. I'm thinking that "coolant" dripping onto your cat may actually be oil... just a thought. Take a close look.
When I wired up the Vtec pressure switch, I used an OBD1 pin, which doesn't really fit perfectly into the clip that goes into the ecu (OBD2 ecu and engine). I bought some OBD2 pins now just in case. Do you think maybe the connection is loose due to the OBD1 pin?
For the leak, I am 100% sure it's coolant. I backed up my car to see what color the puddle was and it was green and when it came in contact with the cat, it was smoking white.
