FWIW my car picked up a good bit of mid-range after doing the vanos rebuild.
I haven't done the PCV and not sure if the prior owner did the work or not! l only had this car for two years and no records of maintenance history prior to that
My car idle is fine. What other symptoms of a failing PVC?

Thanks for the advice
