Have vehicle scanned to see if any codes present
Is the engine running ? no
need more info. does it shut down while driving? shut down on decelleration? acceleration? does it sputter or is it like the key was shut off? is there a loss of power before it happens? does it restart right away or do you have to wait , and if so, how long? is the yellow "check engine" light on: Does it stall every ten minutes until it's fully warmed up?
At what point does it lose power? As you're driving? When you come to a stop? plugged converter
you are introducing more gas to the engine, which gives it more fuel to burn, resulting in more power. and engines have a certain rpm that they run best at. each engine has its own sweet spot in rpm.
One cannot "Calculate the accelaration of a car by its engine power in cc" and hence derive the "force applied by it" because, depending on the configuration of the engine varying amounts of horsepower (ie engine power) can be obtained from the same size engine. One would have to have a known amount of "engine power" to apply the "F=ME" formula and from there calculate the acceleration possibilities.
it means there is something wrong with the spark plugs cause they provide the energy for the engine
(no it uses the energy from the car battery not the energy made by the engine)Yes it does increase consumption because the battery has to be recharged by the power of the engine driving the alternator or the dynamo
If you mean why the difference in RPMs between idling and driving, the difference is due to the engine load; At idle, the engine isn't really doing much other than staying running, but under load (driving) the engine has to put its power out to the drivetrain, hence the symptomatic loss of engine speed (RPMs).
Yes, there usually will be a slight loss of acceleration with the ac on. The ac compressor is turned by a belt connected to the crankshaft, causing a parasitic drain of power from the engine. At highway speeds, the effect is negligible, since the engine is turning at a steady rate.
In simple terms, torque gets you moving and power keeps you moving. In other words, your acceleration is dictated by the torque your engine provides and the top speed is limited by the power.
