Rough Idle

[Chealey]

Hey guys I replaced my EVAP solenoid yesterday on my ve sv6 with a cheap eBay part. I didn’t have a rough idle before replacing the part but now after a few minutes the revs drop and kind of bounce. Has anyone experienced this before?

put your old part back on
there is a reason cheap ebay parts are cheap

Sounds like a vacuum leak, check all the hoses around the area you were working including the evap hoses for correct fitment.
You may have possibly cracked a brittle one removing.
