Cold oil when you first start the engine will have lots of pressure then it will settle down as the oil warms and thins out.
Don't know how cold your cold is but, it could be water in the fuel system (ice).
Surging is the condition where the engine power fluctuates up and down with a continuous, soft jerking motion. When driving at a steady speed, the engine seems to speed up and slow down, without moving the accelerator.
if the engine is cold the computer says I'm cold so rich up the mixture and speed up the engine via TPS. then once the engine warms up another sensor tells the computer it has warmed up and decrease the TPS signal slowing the RPM down.
Their down keeps them warm.
makes it go slower
because inside the engine there are cyilinders that go up and down and whens one goes up it makes a flame to make the engine come more powerful and force the speed to go faster! :) Hope This Helps!
Generally speaking, atoms slow down when cold and speed up when warm.
because the airfoil shape makes tiny air molecules at the bottom slow down and the top speed up. The engine just pushes the plane.
Nothing happens to the forces. The forces are what makes the thing speed up or slow down.
Probably a matter of where the engine's power band is set out, or you may simply be bogging the engine down at lower speeds. Try downshifting and keeping your RPMs up a little.
