Aside from lack of gasoline(or diesel), lack of power may also be driven by drained battery or lack of ignition(ignition system failure). the comment below is correct. it is hard to give a specific answer for this since there are a lot that can cause lack of power and it may variy from car makes and models.


Best to have problem diagnosed with proper equipment. A good shop could run obdII tests, smoke test for vaccum leaks, misfire or lack of ignition. One easy diagnosis is to spray carb or throttle body cleaner in the throttle while giving gas and if the engine improves you have a fuel delivery issue if it stays the same then you have a breather problem. (exhaust leaks, vaccum leaks, or emmission components.

Answerif your whole car completely shut off your distributor cap could have came off. that happen to me one time while driving.

If your car have very little or no compression it can cause you to lose horsepower.

Turning the heat on would actually lower the engine temperature. It's a well known trick if your car starts to overheat. Having the A/C on causes a power loss to operate the compressor, which would also cause engine temperature to go up due to the hot air from the condensor going through the radiator.

Yes. It will seem like your car is "bogged down" or has a loss of power. But before replacing a coil pack, try removing a spark plug and seeing if those need to be changed.
