Don't know what's wrong, but when it's idling, the engine feels bumpy, like random kicks in it. It's not idling low, or misfiring. It can be worse when it's cold. But it stops and it's just a smooth idle when it's in gear though.

Mine has the same issue. For me, the engine is up to operating temp and the idle goes from 650-800 rpm.

Mine has always done this. It doesn't happen all the time. I just figured that's the way it does its thing.

I found my idle got much smoother after adding the PCV side oil catch can.

I no longer have this issue after installing Quantum Solenoids…

 

[Mr. Juicebox]

$750 is a bit steep for this solenoid. Didi you notice any other improvements?

 

[tical2247]

Got them on a group buy for $540, yes it improves the overall drivability of the car. Smoother power delivery. Less of they jerky feeling in lower RPMs if not completely gone all together. Increased throttle response as well. Going to pair that with the redline trans fluid do over all should help immensely.

Are they specific ones? I tried looking then up and found different solenoids. And second, how would you install them

Quantum Solenoids…they are sold out online but there was a group buy in the Hyundai Elantra GT/i30 group on FB.
