Backfiring in the Turbo and TB when starting?

Hey y'all. When I go to start my car sometimes, 5 times out of 10 while turning it over to start it backfires in the turbo and throttlebody, and I see smoke coming from the hood when it does it. then it fires up and runs. I dont know why it does this. It has done it since I bought the car 4 years ago burt it only did it once in a blue moon. Now it seems to do it at least once a day. With the hood up, I and trying it, U see the smoke escape right from the turbo/throttle body section. Smells like someone lit a while heap of matches. When it does it, the boost guage goes to 15 psi boost for a split second. It also seems to blow off 1 or 2 vacuum lines on the throttlebody when it does it. Anyone have any idea whu this is hapening???

:confused:
 
Check you cam sensor setting. It seems like your trying to fire on the wrong cylinder.
 
Hey i checked the cam senson, and I noticed that the whole sensor is cracked and the only part left to the sensor is the top piece with the wires on it. Would this cause that problem? Also could that cause idling problems or is thast only used when starting?
