my 99 honda civic has been having trouble starting only when the car is cold. it started out turning over and then actually kicking on, sometimes with a clunk noise. but now it doesnt make the noise and only starts when i turn the key back and shakes and stumbles, then will run normally after about 5 seconds. i’ve had the ignition coil, cap, and rotor changed, new spark plugs, and the battery is fine.

A faulty coolant temperature sensor could cause cold start problems.

You had the distributor cap, rotor, and plugs replaced. What about the wires?

Could be a leaking fuel injector. That cylinder is flooded at first and does not produce any power. In a few seconds, the excess fuel has been expelled, the cylinder is working, and the engine is running smoothly. A can of good fuel system cleaner like Sea Foam or something with Techron in it poured into the fuel, could fix this.
