Hello and thank you for using

Most common for black smoke is a fuel mixture issue. Most likely your MAF sensor may be falling out of spec and causing your problem. I would start by having the air and fuel mixture readings checked. If out of spec, then the MAF sensor will need to be replaced.

If you have any more questions on this, please feel free to ask. Thanks Jay!
