Smoke coming from the engine when I drive it a little and stop and park it. It starts smoking bad and it’s smell that comes off it I can’t really explain the smell of it

Want crank in the morning and have to hold you gas pedal down and turn a long time for it to start and white smoke come out of it,and clear up in a little while. And it cranks all day long till the next morning...help me please...

My 2016 sorrento v-6 suddenly lost power and smokes huge white clouds constantly

Had some white smoke on start-up although there was a lot more this time but it went after a while and then black smoke started coming out if the engine was under load, accelerating in 3rd or 4th. After about 5 miles the revs shot up to about 4k with no throttle with loads of black smoke out the back. They returned to normal after a few seconds and I drove on, set the cruise for about 55mph. Going through a town I had to accelerate from stop. Got into third and it starts revving again work more black smoke. I put it in 4th and dumped the clutch and this brought the revs back down. It died after a couple of seconds and now won't even turn over. I'm not sure if this is terminal or not yet. Anyone have any ideas what might have caused this?

Smoke from firewall won't start for an hour or so. Replaced both Catalytic converters.

Temp gauge goes up when a. C. Is on ,goes back to normal when you start moving again ,no smoke or steam
