S13 SR Black Runninig Stupid Rich

[240sxinlv]

I have a S13 SR Black and its running VERY rich. It is pumping out black smoke and will soak the plugs so bad they won't fire after only a minute or two of running.

From what I have found its more then likely one of two things. Maf or Coolant Temp Sensor.

It happened out of nowhere. Running fine, took a 5 minute drive, was about to pull into my garage and it started chugging black smoke.

Stock swap. No aftermarket parts worth listing.
