Whenever car idles, it's vibrating a but in the car and I hear something like a deep bass kick roughly every 2-3 seconds. Additionally in the video ( ) there are small burbles and pops when idling. I've already replaced the spark plugs, so it's probably not my spark.

Also my secondary turbo doesn't seem to kick in a my car bogs out around 4k rpm when it's suppose to transition, and it's followed by backfiring and burbles. Probably a vacuum leak but could it be a fuel issue as well?

Any ideas what could be causing these issues? Thanks!

 

You mention a video but no video or link is posted. Did you intend to post one?

 

Apologies, forgot to include the video link
