2005 IQ club car lots of problems!
 
I have a 2005 48 club car IQ got it 3 months ago. Wouldn't get over 9 mph stayed around 8 mph. I can go 20 to 40 yards easing around an it loses all power let off the pedal an it takes off again Repeats this over an over. If I run it up hill or wide open for about 200 yards it slows down to a stop. I can turn it off for 2 or 3 min an it will take off fine. I hade new battery's put in yesterday an didn't help. I can't find a part number on the (mcor). I don't know if it's the speed sencor or the (mcor).

You can do a test to see if it is the speed sensor:

Just from your description it sounds more like the speed sensor. I just replaced both the MCOR and the speed sensor on mine. The speed sensor being bad made the cart go really slow. The MCOR being bad made it really herky jerky.

Not sure if you've got a Club Car DS or a Precedent. A vehicle serial number would help us with that. As far as your diagnosis, do the speed sensor test mentioned on the previous post and see if it passes. If it doesn't, an MCOR issue would be a likely cause for sure. We carry all of these parts on our web store. If it's a DS, the MCOR number you need is AM293101. If it's a Precedent, it's 102528501. As for the speed sensor, it's all according to which motor is on the cart. There are two different ones. One is grey (GE) and the other is black (ADC). You'll need to identify your motor before you order a speed sensor. Do NOT buy a cheap speed sensor from Ebay or Amazon or you'll have the same problem again in less than a month.

It's a 2005 Club Car DS IQ with an ADC motor.

The buzzer is mounted on the back of the center dash panel directly below the key switch.

Yes. That is the correct speed sensor.

I changed the speed sensor this fixed everything except after ridding slow in the woods around 5mph. The cart slows to a stop an after a min sitting there it will take off. It will run for 100 to 200 yards an do the same thing unless it's running wide open. I believe something is over heating.

This is a safety feature of the controller known as "Thermal Cutback"

When the controller gets to 80 degrees Celsius, it reduces power until the controller cools off. Usually it happens when towing or driving slowly for a long period of time.
