Default Rough Idle, Tried Everything, what about this....

Hey Guys,

So ever since I replaced the head gasket on my ti, it's had a rough idle. I've replaced all the usual culperets (PCV valve, ICV, etc.). I'm wondering if the chain tensioner could have something to do with it because I can still here the chain moving a bit, almost like a lawn mower. Also, when I'm driving and come to a stop, the idle stays temporarily good, then starts to get rough after a few seconds. When the idle is rough, it almost sounds like a diesel. Just want some input to see if it would be worth replacing the tensioner.

Thanks,

Chad
