My 1.7 FI is suddenly running rich. I have not changed anything i am aware of. I sometimes have a lose injector plug but that's it. Any suggestions where to start troubleshooting?

Take a look at this webpage: http://members.rennlist.com/pbanders/DJetParts.htm
You could have an MPS (Manifold Pressure Sensor) that has a leaky diaphragm, that would cause you to run very rich. Or an open CHT (Cylinder Head Temperature) sensor could cause a rich situation. The website linked has a lot of troubleshooting and parts information that could help diagnose this rich issue. |

Won't start with an open CHT. I would persue the MPS and the hose connecting it to the intake plenum. The Cap'n |
