182 low power when cold

[car.crash]

My car won't go over 3k in the rev range and feels like it's dragging a house.
This isn't the usual morning splutter what they all suffer from.
Once it warms up it feels ok but the issue is getting worse over time. Any ideas?

New spark plugs?

Crank sensor needs cleaning?

They are rough when cold, shouldn't be going over 3k when it's cold either

Wait for it to warm up..

Probably sparks though as above.

Regardless of what I should be doing. The car will rev above 3k normally.
I have a steep hill to climb on the way out of my house but the engine is holding back. It's not the usual cold stutter, it's much worse.
The power vanishes and the car will virtually stop.
