PCV / Coils / Plugs / MAF / TBPersonally, I would scan it to see if there's a misfire recorded and which bank.I'd check the plug gaps and perhaps replace if due.Definitely look at swapping the PCV and go from there.
A Misfire not potentially caused by faulty plugs or coils...
Exactly the same as what I had, sometimes it would do it and others it wouldn't. It's the pcv, change it and it'll be fine.
