poor vacuum and codes P0341 and P1347
 

okay.. so i was running the car hard the other night and all of a sudden i notice poor vacuum at idle and those codes for cam signal implausible and bank 2 cam crank sync malfunction.. or what ever. due to the vacuum i think its mechanical, like the belts jumped time.. or a bad adjuster.. any ideas??

belt is shredded. ill know for sure tomorrow evening if its jumped time, although it looks like it has.. thatll give me all of these problems...
