    Boost Fuel problems

    Okay so My 04 ecotec cavalier is running rich...so rich it misfires alot, its got this weird jerky sluggish acceleration, my boost is like -10 to -15 vacum untill about 4,000 rpms then jumps to 5 psi...Is it cause of my fuel problems, should i check the turbo my waste gate??...what about my fuel its really weird i have stock injectors and i'm running like 11-12 AFR then soon as i touch the gas goes to 10 maybe lower but my gauge only goes to 10...I have a fuel pressure and 42lbs injectors i'm going to put in next week, you think this will solve everything?

    what are the stock injector rated..??
    I sold a set of 34lb injectors(stock cobalt ss/sc) to a turbo cavi owner and he loves them. They hooked right up to his harness even.
