Engine Revving Up and Down at Idle FIXED

Car won't idle normally? Engine surges or revs up at idle? Mine used to as well, until I discovered what the problem was. I replaced multiple parts that may not have been needed to fix this issue. Hopefully this video help someone else out.

The car used in this video is a Hyundai Elantra 2001. Same or similar engines: Hyundai Accent Elantra Tiburon Tuscon Kia Spectra5 Saab 9-3 9000
