871 Issues

[Rawze]

Black smoke on an 871 is almost always too much fuel with not enough air.

== Restrictive intake?... (After-garbage brand CAC or maybe turbo issues, etc.)

== bad de-mandate programming over-fueling it?.

== Clogged up exhaust or intake issues?.

== Turbo issues?.

== EGR valve stuck open?.

== incorrect fuel pressure reading to ecm?.

== non-oem components and now it has wrong compression ratio or low compressuion due to poor quality cylinder head, or incorrect, non-oe pistons, etc?.

== sounds like a cluster-f$$k to me if some yahoo used non oem parts, and then expected it to run right. - Not gonna happen. - they got what they paid for.
