fOULED sPARK PLUGS
Hi,
I am having a problem with my 86 C4 running really rich and fouling the plugs, Plugs are black as black can be and smell of fuel. I did upgrade the injectors to Bosch, not sure if that is the problem. looking for help.
Thanks,
Jim

Have you checked your 02 voltage to see if the sensor/sensors are functional, if you have No knowledge of it ever being done 02 sensors are a Maintenance item.
Also is the car breathing well, while driving can you get it to rev into 4000s under load. If it seems clogged up it could be a the catalytic converter problem
