The c191 is the round plug below the manifold on late models (88+??) that connects the fuel injector, engine coolant temperature, temperature gauge to the main wiring harness. The general consensus seems to be that moisture and other elements seep in over time and cause a bad connection. The result is erratic engine behavior presumably caused by the coolant temperature sensor, which controls timing, fuel, and other essential ingredients in producing smooth, reliable running conditions.
I haven't yet pulled back the rubber on the harness to plug connections, honestly I hadn't even thought of that. I just examined the pins and they do have that light green copper look to then. Originally I scuffed them with sandpaper and used dilectic grease, but my issues are still present. They are random at best (sometimes my car runs perfectly) but when they do pop up...my car dies instantly abs I'm stuck pushing it through traffic to the side of the road. I'm thinking a hardwire will be in the near future...
I like the process of elimination idea, but unfortunately I don't have a disposable income to use troubleshooting parts.
To answer the question above...I'm using m50 green top 17# injectors, not s50. Supposedly the spray pattern is the only difference (4 pintle vs. 1??) which is said to possibly increase engine efficiency.
