Please help Rich condition
This past weekend I pulled the plugs and I had acouple of plugs that were black. 
I know that this is an indication of a rich condition but what would cause this. What can I do about this. Please help.
BTW it is an 90 coupe. Thanks in advance.

With a multimeter, measure the ohms of all your injectors, they should all read within a few tenths of an ohm from one another, in the 16 - 17 range. If they pass when the engine is cold, redo it when the engine is at operating temp or vice versa. Your year of Vette with the grey injectors is prone to electrically shorted injectors.
