Basically when I take off from a stop in first gear the car shoots out a puff of what appears to be black smoke but after that it won't smoke at all while cruising or even in neutral I can rev the heck out of it and no smoke but when under a load on take off it will.

These are the codes I keep getting P0171 P0174 P0136 P0141

And I still have that exhaust leak on the passenger side where the X Pipe meets the Header , one of the bolts were loose. I tightened it all the way as much as I can but I can still hear it hissing.

I'm gonna try loosening the bolts again and re tighten them.


Any help here is gladly appreciated.

the smoke, if comingg out of the exhaust, may be a result of the car running rich
