Well I just got my 1.7 d jet motor back all together and all in my car. After messing with the timing a little bit, it fired right up and ran pretty well. It was late, so I quit on it for the night. The next day I came out, and all of a sudden it was running rich. Extremely rich, black smoke out the tail pipe and all. And this was without touching anything. I was just wondering what might go wrong with the injection to cause this. I tried to get it to idle for as long as possible so it would get warm, but it was rich until it didn't want to run any more.(probably 20 minutes at an idle). Any help?
I'm back at school now, so I won't be able to work on it for another couple months, but it would be nice to have some direction, or maybe I can talk my dad into messing with it. thanks |

With the d-jet you want to make sure that all of your components match - ECU, MPS and TS2. These components must all match and be for a 1.7 for it to run *correctly*.
As per usual - check out Brad Anders' d-jet site for more information on this than you ever wanted to see, but it is THE MOST VALUABLE site out there for us d-jet owners. If all of your part numbers are correct, start testing components starting with the TS2 and the MPS. A malfunctioning cold start can also cause a rich-running type situation. There are a lot of variables, so you need to start small and make sure that things like your ignition is functioning properly (plugs good, gapped correctly, plug wires good, cap, rotor good) and move on from there. Always start with the simple things first and work up from there. |
