2. Slipping transmission: The transmission may be slipping, preventing the engine's power from being effectively transferred to the wheels.
3. Low transmission fluid: Insufficient transmission fluid can cause the transmission to slip and overheat, resulting in the symptoms you described.
4. Faulty torque converter: The torque converter is responsible for transmitting power from the engine to the transmission, and if it is malfunctioning, it can cause the engine to race without producing enough power.
5. Faulty sensors: Faulty sensors, such as the throttle position sensor or oxygen sensor, can provide incorrect information to the engine's computer, causing the engine to run poorly.
6. Vacuum leak: A vacuum leak can cause the engine to run lean, which can lead to increased RPMS and reduced power.
7. Clogged fuel filter: A clogged fuel filter can restrict fuel flow to the engine, causing it to run lean and lose power.
8. Faulty fuel pump: A faulty fuel pump can fail to deliver enough fuel to the engine, causing it to run lean and lose power.
9. Worn-out spark plugs: Worn-out spark plugs can cause the engine to misfire, which can lead to reduced power and increased RPMS.
10. Faulty ignition coil: A faulty ignition coil can fail to provide enough spark to the engine, causing it to misfire and lose power.
11. Head gasket leak: A head gasket leak can allow coolant to enter the combustion chamber, which can cause white smoke and reduced power.
12. Cracked cylinder head: A cracked cylinder head can also allow coolant to enter the combustion chamber, causing white smoke and reduced power.
If you are not mechanically inclined, it is recommended to have your vehicle inspected by a qualified mechanic to diagnose the exact cause of the problem and determine the necessary repairs.
