What are the reasons for poor acceleration and inability to gain speed?
1 Answers
The reasons for poor acceleration and inability to gain speed are: 1. Engine misfire; 2. Clutch slippage; 3. Low fuel pressure; 4. Dirty throttle position sensor or voltage imbalance causing electronic throttle failure. The main causes of clutch slippage are: 1. Insufficient friction on the clutch friction plate; 2. Forcing gears or disengaging gears before the clutch is fully engaged; 3. Driving for long periods with the clutch partially engaged or coasting with the clutch pedal depressed. Applying sudden throttle when gears are not fully engaged or disengaged can cause abnormal wear on the clutch plate. Low fuel rail pressure usually also leads to similar symptoms of weak acceleration and inability to increase engine RPM.
