    hey guys been a while since i been on here so i got a dark smoke coming from my exhaust my buddy thinks its running to rich a few months ago my turbo went so i just got done replacing it with a 16g and replacing the exhaust manifold while i was in there so i think videos do more justice and trying to point out the issue so i will post the video the computer pulls up codes to fuel pressure regulator also my car idle surges when it goes to a high idle sometimes and then the idle goes down and up almost like im reeving it up also the o2 sensor for the downstream tripped as well any suggestions besides the parts im replacing this week the fuel pressure regulator and the idle control valve and o2 sensor for the downstream thanks in advance

    Is the 16g new? Almost looks like blueish smoke which would indicate oil in the exhaust.

    Hopefully it ends up being that simple. Good luck!

    Looks like oil smoke to me as well...not saying it's not possible for the car to be rich, but rich smoke normally has a "heavy" gasoline odor while oil smoke is a bit lighter in color and odor. If the head's never been off the car that's a good place to start, usually the valve seals are hard as bricks and the guides may have some wear as well. Leaking valve stem seals will also overrun the factory PCV system by putting more pressure into the crankcase than it's designed to handle and prevent the turbo from draining properly which can also cause excessive smoke and eventually ruin the turbo.

    Maybe to a boost leak test for the surging and do a compression/leak down test to make sure it’s not a bad head gasket or bad rings.?
