Car sluggish on 1st crank and stays that way until 2nd crank

[TheAnswer_03]

First cold crank in the morning, the car feels somewhat sluggish. The brake, gas, steering feel stiff; I have to push the gas harder to accelerate. I know a fully warmed up car will run smoother, but I drove for an hour and no change.

However, if I turn the car off and crank it later when the car is already warm, the car feels much more responsive and wants to go at even light throttle. What's causing this? Will grounding the throttle body help?

I experience the same thing on cold days. I warm up the car until I hit under 1000 RPMs before I start driving. I stopped noticing this issue after letting it warm up.

I'm not sure why it still behaves the same after driving for 20-30 minutes.
