Re: Help Help Help Help bad gas milage (craiger)
A.) why is he running RC270's without tuning?
B.) that code will indeed cause the car to run in limp mode where it enriches the air/fuel mixture to the point of halving your gas mileage.
C.) the combination of bigger, untuned injectors and limp mode will do that. Check the O2 sensor too: it'll probably be fouled at this point.
