2 white plugs 2 black 200

I have never had an injector go bad. They are quite heavy-duty and should last the life of the car. Having said that they could be clogged up. I would try running some quality fuel system cleaner through the tank and see what that does. I would also check the fuel pressure, it could be that the regulator is shot or the return line is clogged (causing high pressure). There may also be other reasons why your car is running rich but this is how I would start to troubleshoot the problem.

How is your gas milage?
