What are the reasons for the lack of power during acceleration when the Besturn B70 is warmed up?

The reasons for the lack of power during acceleration when the Besturn B70 is warmed up may include: System malfunctions: Air leakage in the intake system; fuel pressure too low; clogged air filter; faulty water temperature sensor; faulty air flow meter; malfunctioning idle control valve or additional air valve; cold start injector not working; fuel injector leakage; incorrect ignition timing; broken wiring from the start switch to the computer; cylinder compression pressure too low. Poor ignition system performance: For example, aging ignition coils or spark plugs that have not been replaced for a long time can lead to insufficient ignition energy, poor combustion, weak engine acceleration, and the engine warning light turning on. Replacing ignition system components can resolve this. Fuel system malfunction: Fuel system malfunctions can cause the pressure to be too low and the fuel injection volume to be insufficient, resulting in weak engine acceleration. It is necessary to inspect and replace the fuel filter and fuel pump.
