Most likely your MCOR is going out. Key off, pump the pedal 25-30 times, if it works better after that, contact Revolution Golf Cars and order an OEM replacement. https://www.revolutiongolfcars.com/mcors

Where did you get the MCOR - I hope not Amazon or eBay? If you got it from David, it is an OEM and should not be doing that unless there is another underlying issue. If you did get it from him, a quick phone call gets you going the right direction as he will walk you through any checks on the phone to see if it is faulty or what else it could be.

If you have verified the signal to be stable and correct from the MCOR, your next testing would be the controller output. (Input is from the MCOR)

What year is the cart?

What is your pack voltage when trying to accelerate?

You hook a digital volt meter or multi-meter up to the pack and lay it on your seat whilr you ride.
