yes, you are causing it to run richer.
Check the fuel filter or the fuel pump.
acceleration is a measurement of increased speed change (deceleration being that of decreased speed change). your current speed (Whether fast, or slow) is irrelevant, as long as it changes, and increases, which means you are accelerating.
Yes, accelerating from a standstill typically uses more fuel than maintaining vehicle momentum in slow-moving traffic because the engine has to work harder to overcome inertia. In slow-moving traffic, keeping a steady speed and avoiding unnecessary acceleration and braking can help conserve fuel.
it depends what speed is fast and what speed is slow and what car you are talking about.
By D-accelerating
not a fast but slow

Fast moving stream
* How would you describe the pace at which you work? * The pace of work has been dramatically accelerating since the mid 80's and now approaches what could be described as instantaneous.

Fast moving. sediment is heavy it settle out in slow water. But a river that just became slow after being fast looks like it has the most, because of all the settling going on.
