Hi, I am having a issue with the forklift stumbling. Starts and runs fine but at idle it will stumble like it's about to die for about 1 second, then run fine again. This happens about every 5 to 10 seconds. If I give the unit throttle it will rev up, but it still stumbles, about every 5 to 10 seconds at higher RPM's.

Thanks in advance for the help.
