My car doesn’t want to go up hills. It has slow acceleration, and feels like it’s not kicking into the next gear when I drive it.
My car has an automatic transmission.
What you are describing sounds like you may have a clogged catalytic converter. The catalytic converter converts toxic exhaust gases into less harmful pollutants that are suitable to be expelled into the atmosphere. When the catalytic converter is clogged, this causes these gases to be backed up into the exhaust system not allowing the engine to breathe properly. When this happens, the engine is forced to work much harder to expel these gases. This often results in the engine bogging down, hesitating, shaking and causing very poor fuel economy. This should also cause a check engine light to come on as the O2 sensors should be reading the incorrect amounts of oxygen in the exhaust gases if this is your problem. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your catalytic converter.

When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive. This means you can`t get the power you need if you`re trying to accelerate when overtaking or going uphill.
When you press down the accelerator pedal and get minimal output, it could mean you have a problem with your fuel system. The most probable issue is a clogged fuel filter. Your fuel filter works to ensure that dirt and debris do not get into the fuel system.
A poor fuel delivery drains out the power of the engine resulting in poor acceleration. Fuel filter – A dirty or clogged fuel filter affects the fuel supply to the engine and thus the engine has low power causing poor acceleration. Other parts of the fuel system are the fuel injector and fuel pump.
Over time, the transmission fluid gathers dirt and grime. This can cause the engine to run roughly, stall or fail to accelerate when you press down on the gas pedal. You may need to have a transmission fluid change before more damage is done.

Your issues with the air conditioning unit are likely unrelated to the issues with your engine, and you will likely need your AC unit inspected in order to diagnose that issue.
From what you describe it would appear that some sort of serious issue may have occurred that is greatly affecting engine performance. A few common reasons why a car would not want to go over 45 mph is due to problems with the fuel, ignition, or engine management systems. Smoke from the engine is usually a result of fluid leaks. It may be possible that oil, power steering, or even brake fluid are leaking and have made contact with a hot engine component, producing smoke. You mention that the car did not want to stop, or had trouble stopping – this could be related to the smoke if there is a brake fluid leak present. I would recommend having a professional technician look at the vehicle, as the possibilities could be many.
