Tick almost knock during idle

Sorry to hear about you car problems. This could be a few things including valve train issues. It's going to be hard to say for sure without listenging and I'd hate to see you waste money throwing parts at the issue. Best bet is to have a local shop take a look. Also double check with the dealer that you don't have any powertrain warranty remaining. Here is a link to find a shop near you. https://repairpal.com/repair-shops Alex
