Thanks for taking the time to read this. My '04 manual with 103k miles on car,
35k miles on latest replacement engine.

On starting the engine there is a misfire on rotor #1 with white smoke out of the exhaust on cold starts, just a rough idle for 15-20 seconds on starts after shopping or whatever. After the engine clears itself, the motor runs perfectly. For 100k maintenance and to resolve this problem I have done the following:

-New coils, plug wires, and spark plugs
-Seafoam to TSB
-Cleaned and re-set ESS
-Cleaned MAF with MAF sensor cleaner
-Took to dealership for compression test, came back with flying colors
-Dealer pressure tested coolant system and said cap leaking, replaced with new factory cap.
-Dealer could not find a solution and had trouble replicating problem, although it happens to me 100% of the time on starts where the motor has been off more than 30 minutes.
-Despite new coolant cap, I've re-filled coolant tank 3x but no evidence of coolant leak around engine or on garage floor.

Ok, this morning I removed airbox and noticed all the accordian grooves in the intake pipe between airbox and throttle body were full of coolant. Also, the tray under the airbox was wet with coolant.

My theory now is that coolant is getting into the intake and being sucked into cylinder #1 on cold start-up causing misfire until the coolant clears.

I need help troubleshooting how coolant is ending up in the intake. Any help would be really appreciated. I'm dating an amazing woman with a perfect body and leaving the movies, walking to my sweet car, then having to wait a minute while it sputters and blows white smoke out of exhaust is not helping me seal the deal!
