Unresolved P0133 issue

Hi all, I'm new here and could really use some help. I have a 2008 FG XR6 Turbo with 240000km on it. It has the ZF six speed. For a while now it has been running a bit weird. I will be driving, mostly when it's cold or warm and it will make a weird kinda vibration noise, revs will drop by approx. 400-500rpm for the duration of the vibration. It will do this up to 7 times. It is intermittent and each vibration lasts for approx 0.5-1 second each time. I have googled it and even bought a Bosch OBDII reader and it came up briefly with trouble code P0133 . I have replaced the o2 sensor and it fixed the issue for a day. I found that the hose that runs from the PCV valve was snapped, so I replaced it with some fuel line hose and it fixed the issue for 2 days before starting. All the manifold bolts are tight and I even checked it for leaks and found nothing. It doesn't do it while on boost, only while on vacuum. Turbo has minimal play for a car of it's age. It is starting to do my head in. Any help would be greatly appreciated.

 

Cheers

hmm... seems like either you have a vacuum leak somewhere (a smoke test is the way to go to be sure) or the gearbox needs a service.
