My truck is 1995 Chevy S-10 with a 4.3 V6 and it is MPFI and it is running rich. I have replaced the spark plugs, egr valve, spark plug wires, spider fuel injection, and my check engine light is NOT on. The little computer that you hook up to the truck says that all the sensors are working fine. I also must add that it is a mid year truck. It was made late 95 early 96. What could be my problem??
