My 2005 ez go electric,golf cart when i push down on the pedal slowly it moves slow and now power?

The issue you are experiencing with your 2005 EZ-GO Electric Golf Cart could be attributed to several factors. One possible cause is a low battery charge. Over time, batteries can wear out and lose their capacity to hold a charge, causing a decrease in power output. Another potential issue could be a faulty motor or motor controller. If the motor is not receiving the correct amount of power, it may not be able to generate the necessary speed and acceleration. It is also possible that there could be an issue with the throttle mechanism or pedal sensor, which could affect the responsiveness of the cart. Finally, it is worth considering the age and overall condition of the golf cart. Components can wear out over time, and regular maintenance and check-ups are essential for optimal performance. We recommend consulting a professional golf cart technician to diagnose and resolve the problem for you.
