My car sputters when I first accelerate after sitting for a minute, it sputters out white smoke that smells bad like burned fluid. I have recently changed my oil and have no mix of coolant and oil. Also did a 3 point check on coolant and no oil mixed in. I replaced the throttlebody recently and this was a problem before i changed it. I have also taken off the egr valve and cleaned it out really well. I replaced the engine filter as well. After it sputters and i able to start driving normally it runs fine. It also runs fine in idle. ---

Are you using either oil or coolant? Any check engine light? ---

I have a feeling when its blowing smoke that it is burning a little oil each time, but im not sure about that. There was an evap code for minute before i replaced the throttle body but went away after i replaced it. ---

Coolant leaking into the combustion chamber can produce a white smoke and an Odor. ---

Wouldnt I have coolant in my oil when I changed it? I know a lot can cause that especially a head gasket, but is there something common that can cause that? ---

Leaking valve guide seals can drip oil into cylinders while idling, then generate smoke while pulling away from a stop. ---

Would that cause bad acceleration and sputtering? Again this is intermittently it doesnt happen constantly or all the time. ---

Depends on where the break in the gasket is. But you can pull the plugs and see if one is nice and clean and the others aren’t. ---

As a a follow on, a cylinder pressure test should tell you if there is a problem cylinder. If there is low pressure it’s the head gasket, valve seating, or rings.
