Default 2005 Club car jerking at half throttle and loss of power on hills

Our 2005 electric Club car has a slight "jerking" motion to it at 1/2 to 3/4 throttle but runs fast and easy at full throttle. It also has trouble climbing hills...it seems to lose power (barely creeps). However, at full throttle it does fine. The problem is, it's really not safe to climb our hill full throttle due to ground holes, bad terrain, ect. Batteries are 3 years old, clean, and we had someone at a battery store check them. They said they were all reading fine. Has anyone had this problem or suggestions for trouble shooting?
THanks for any help!

You have the symptoms of a bad MCOR. What's the serial number of your cart? There are lots of different versions and I want to be sure to point you in the right direction.

This seems to be the number one issue with Carts containing MCORs, if a Sticky with jerking or jumping throttle with the information about how to identify the problem would help with the continual help questions on this topic.

There are always going to be folks who holler for help before doing any research. My grandkids have the same reflex.

I had the same problem with my club car and I greatly appreciated the help. The MCOR / jerking at slow speeds issue should be a sticky, which would make it easier to find whilst doing research. I looked at the stickies first and still had to ask (holler) for help.

I sure hope I'm not jinxing myself. But I drive my cart a lot every day seven days a week. This makes me think the lack of use is the problem with the MCORs. So far mine is working great on my 2003 cart.
