Fixed..Black smoke away,,,
So finally got rid of black smoke when accelerating..
I bought an obd2 lead for my laptop and used forscan to read/clear codes...Only code that ever showed was P1103 (maf higher than expexted)
Heres what i did...
1. Cleaned MAF sensor with carb cleaner wasnt really dirty (no better, still same black smoke)
2. Cleaned MAP sensor with carb cleaner, was totally covered in tar like gunk (tiny bit better, but still lot black smoke)
3. Disconnected egr sensor plug (black smoke gone and van seems to be more reponsive)
I know have codes P1409 and P1402 which are because ive disconnected egr..
How is it possible that the egr was causing black smoke? I thought black smoke= over fuelling
I think your problem will be resolved by a process of elimination, possibly the above will be just a starting point. There again it might just work.
Good Luck!
