I doubt the CVV and associated hoses are causing your problem.
You have a persistent cylinder 1 misfire.
This is going to be coil, sparkplug, or fuel injector.

If it is the crankcase ventilation/oil separator issue, can I DIY???

I remember last time it cost me hundreds of dollars to replace this piece that connects 100 hoses together....

Thanks!!!!
