Misfire at high revs after replacing pcv to inlet breather hose on 97 E420

Wondering if people can help here. The breather hose was in complete tatters on my 1997 E420. This is the funny shaped hose that runs from the rear right side of the engine to just under the inlet pipe on the M119 engine.

I had to remove, then reinstall a sensor that sits on the side of the inlet in order to fit it.

The car seemed to run well after i put everything back together but at high revs, the engine has a misfire. The it does catch itself and go back to normal at the lower rev range.

This seems to only happen at 4000rpm + and it will not rev much higher/

Any thoughts as to what the problem is?
