What Causes Frequent Engine Revving Without Acceleration While Driving?
2 Answers
Frequent engine revving without acceleration while driving can be caused by issues with the control system, cooling system, or clutch plate failure. Control System and Cooling System Issues: If there are no problems with the transmission itself, the issue may lie with the control system or cooling system. When the vehicle is moving steadily, sudden engine revving may occur, but normal operation resumes when the speed decreases. This happens when the transmission abruptly shifts from a high gear to a low gear in a short time and fails to respond promptly. The solution is to reduce speed and allow the vehicle to cool down. Clutch Plate Failure: Brake clutch pressure leakage can cause slipping, which may result from insufficient oil pressure in the transmission valve body or problems with the buffer plate, leading to transmission slippage. The solution is to visit a 4S shop or repair shop for fault diagnosis and repair.
I've been driving for over a decade and often encounter this issue - the engine revs up when I press the accelerator but the car doesn't surge forward. This is most common with manual transmissions due to clutch slippage. Worn clutch discs or pressure plate problems prevent power from reaching the wheels. Prolonged highway driving or aggressive acceleration can accelerate disc wear. Check if the clutch pedal has excessive free play. Insufficient or contaminated transmission fluid can also cause poor performance. Additionally, a dirty engine throttle body affects air intake, or a stuck accelerator cable may be the culprit - manual adjustment or cleaning can help. Don't underestimate this problem - revving not only damages the engine but also wastes fuel and delays trips. I recommend visiting a proper repair shop soon for diagnostic equipment testing. Drive gently in daily use and avoid frequent hard acceleration.
