incorrect fuel to air ratio. usually the cars computer or ECU has not adjusted the fuel ammount to compensate for the extra air intake due to acceleration
It is the alternator....
Lack of propulsion.
AnswerIf you are having problems with power while shifting and accelerating have your fuel censor looked at. You may need egr valve checked .You may need intake decarbonized .You may need mass air flow sensor .
dirty fuel filter
start with the spark plugs
A plane may stop accelerating due to reaching its maximum speed limit, encountering headwinds that counteract its forward motion, or due to the pilot intentionally reducing engine power to maintain a specific speed or altitude.
Loss of power when accelerating can be caused by a number of things. A leak in the fuel line or even a bad alternator can cause this.
Hesitation when accelerating with tha a/c on is a common occurence with four cylinder vehicles. The a/c uses alot of the engines power and causes the hesitation. It is not usually a cause for concern.
you have a vacuum leak
Burning rubber, or screeching the tires, and then accelerating.
Bad ignition coil
unburnt fuel
