this is the video I made of my car a few days ago, I'm concerned about the water dripping and smoke coming out of the exhaust when I revved the engine to red line.

the condition was: the car has just been fired up from the night before, idled for 10 mins before I started revving the engine, temperature outside was around 40 degrees, and it just snowed here a few days ago. I understand cold air condensation is normal, but when I saw the puddle of water came out, I was a bit worried.

thank you for your opinion.

sorry forgot to say my ls400 is a 94, never had any mechanical problem.

cold air condensation+ you were probably running your air conditioner at some point in the near past. OR the car was just running really rich and the cold start injector was dumping fuel.

either way, sounds normal enough.
