Either you are reviving the engine, which can easily be heard, and wasting our time or you have an issue with idle control.

Hi guys. If is idle control need engine need to change sound? In my case sound is same. Sometimes when driving needle jumped. Yes maybe is broke. How to fix? I didn’t put any information bcz I don’t know how to explain this. Will be appreciated for help . Thx Ed

when I cranked up the sound on the video it sounded like the engine was getting louder.

After hitting on the top needle go to 500 rpm. After that I press gas pedal to show needle how is moving hard and jumping
