Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.
Why does my car lose power when idle?
When the EGR valve gets clogged, it may get stuck open or closed, meaning exhaust gas will continue to flow or not flow at all. When this happens, it affects the air/fuel ratios inside the combustion chambers, which can lead to a loss of power. Not enough power, and you’ll have stalling problems while idling.
Why is my engine shaking and losing power?
Air or Vacuum Hose – Another common cause for engine vibration and power loss is when air or vacuum hoses come loose, begin to leak, or rupture.

More important, small problems often hint at larger ones. In addition to the glitches already cited, your car’s MIL could point to a bad positive crankcase ventilation valve.
Why is MY BMW X3 losing so much power?
Bad spark plugs, fouled-up plug wires or a cracked distributor cap can cause spark loss, while compression loss — in which too much of the air-fuel mixture flees a cylinder before going bang — commonly arises from a leaky exhaust valve or a blown head gasket.
