Reprogramming engine management system on yardsport 700xlt

[jsm2006]

I have a 2012 yardsport 700xlt that started with a high idle, I changed out the throttle body but it was still too high. I then messed with the throttle cable positioning and now it will run for about 30 sec. and then as soon as I touch the gas it sputters and dies like its getting too much gas. I've changed out the filters and checked the pump. It could be something completely else but a mechanic told me to reset the engine management system but all I know to do is take the battery cables off and touch the 2 ends together.

I believe my 2015 HiSun you hold the gas pedal to floor and let it hit the rev limiter for 3 seconds and shut the key off.  Im sure someone else will chime in and let us know if I am incorrect. Hope I was some help.
