Rev Problem

ლ(ಠ益ಠლ)
Alright so i can't figure out what the deal is with my car (it's an auto). Increasingly recently, it's been doing this thing where while i am just coasting like downhill or whatever (foot off the pedals) the revs will go from about 13-1400rpm to about 16-1700rpm and back down again and keeps doing this until i either slow down a bit or push the gas pedal a little bit.. So my question is what is the deal with this? If anyone else has run across this problem in the past, how did you fix it? Thanks in advance...

throttle position sensor or you IAC. either one would make it do that. mine goes from 1000 down to like 200 then back up because i havent adjusted my tps yet but if you have a stock throttle body and its the tps your cheapest option is to buy a aftermarket throttle body and new tps. stock throttle body from a dealership runs between 650-800 dollars.
