Welcome to the site! I may be a little biased, but I think we've got one of the best ATV/UTV forums on the ole interweb right here
That said, start with the basics, on that idle hiccup. When's the last time you swapped in a fresh set of plugs? These hi-po motors don't respond well to short run-times, can foul plugs quicker than you'd expect. Gotta run 'em up to heat
I don't think it's your MAP/T sensor responsible for the issue. The IAC (Idle Air Control) valve would be the one I'd focus on. You can remove it and check for drag or sticking as it actuates, clean if need be, and reinstall without needing any special tools or programs. It's on your intake tract just below the air box. Download your free service manual and search the site here for all the particulars.
