Govin Posted March 11, 2024 Share Posted March 11, 2024 (edited) Hi guys I have a Nissan Bluebird Eprise, SU14 manual. It’s been 3 months since I bought it and it’s having black smoke, do you guys know what could be the potential issue? I’m hoping it doesn’t need a major engine repair which would cost me a hefty amount. Edited March 11, 2024 by Govin Quote Link to comment Share on other sites More sharing options...
wildwise Posted April 6, 2024 Share Posted April 6, 2024 Sitt having trouble? My guess is bad air/fuel ratio. 1. Too much diesel (lean condition), need to adjest pump & injectors. 2. Low airflow, Clogged or bad air filer / line. 3. Airflow Sensor (MAF) or Oxygen sensor fault. I own a 1999 made manual U14. Some parts of the wiring was f****d by some idiot. I didn't have any experince in automobile field. But mostly I do the little repairs at home myself. Quote Link to comment Share on other sites More sharing options...
