Q: Acceleration issue, RPMs increase but not speed

asked by on

Hello. My car has acceleration issues. It starts great but has difficulty increasing the speed even thought the RPMs are revving. I had the spark plugs and a sensor replaced. I took the car to several shops but nobody found anything wrong with it. They checked the catalytic converter as well and it is fine. I still have the problem. What could be causing it? I appreciate your help.

If your car is revving up but not moving, or is slow at gaining speed, then you have a slipping clutch. If you have a manual or automatic transmission it will still be a clutch issue. A mechanic with experience will need to road test the car to verify the problem if it is indeed the clutch causing the problem. If you want to have this done, a professional from YourMechanic can diagnose your vehicle's slipping issue and let you know what should be done.
