The PCV is located on the intake manifold between the 3rd & 4th injector (facing engine, right side, just on the other side of the valve cover).
Be aware that the VX PCV is merely a hollow 90deg tube with no 'one-way' valve in it (that is down by the collector box on the engine) so when they sell you one at the parts store, be sure to get the right one.
Sounds like it could be a vacuum leak (what isn't!) Cleaning is a great start to help narrow things down but isn't always a cure-all.
One idea... did you reset the ECU after cleaning? This is done by simply pulling the 'backup' fuse(should be labled as such) for about 30 sec (with the car off, of course) and putting it back in. This should be done , btw after any kind of work on any part (or system) that has an electrical connection.
One other thing that may have happened, is that after the cleaning, your Throttle body might be feeding too much air into the system and the ecu is trying to constantly adjust. Download the Helms manual (don't have a link but google it) and follow the procedure for adjusting idle. After I rebuilt my intake manifold, I had a similar problem. *Properly* adjusting the idle fixed it for me after the cleaning. As I recall (but VERIFY w/manual), the procedure is to pull the IACV connector after the car is warm, adjusting the idle to a bit below normal idle speed (normal=600rpm?). Turn the car off, reconnect everything, remembering to reset the ecu.
...more as it comes to me.
