2013 Versa car surges or lopes as if not getting gas, please help

If idle problem, clean the throttle bore and around throttle plate, don't force the throttle plate. It appears you have drive by wire throttle. how long since a tune-up? Any applicable trouble codes? I have a 013 nissan versa. Haven't had any problems with mine. I don't know much about this vehicle? I got a, it's not a service manual exactly, it's a service dvd for my vehicle. It has wiring diagrams and everything. Nissan USA wanted 200 bucks for dvd back then. I went to nissan Canada and bought the same dvd for 10 bucks. I believe I found it on ebay, not sure? Nissan usa would let you rent their database for a small fee, I can't remember how much? I wanted the dvd because I didn't know anything about this vehicle. Anyway, good luck
