From reading the forums it seems many favor CC's, while some don't run them and don't report any issues. Some have mentioned that it may be variance in the PCV from car-to-car. I was averse to installing one initially, but if the MAF is getting dirty prematurely and I don't have an oiled air filter, then I think this must be the issue. I rubbed the MAF housing with my fingers when cleaning it, trying to tell if there was a film of any sorts on it, but it didn't seem dirty. However, hitting it with the spray cleaner did fix the car right up. I'm going to wait a few more miles and see if the P0172 code comes back, and if so will put a can on the PCV side.

Only ran a can on the PCV side. The crankcase side i ran to an open filter and capped the intake nipple. If you keep having to clean the maf, that setup is worth a try.
