2009 Chevrolet Corvette Coupe 6.2L with engine code P1174, what is the meaning of the code?
P1174 Fuel trim cylinder balance Bank 1
This code condition means there is a lean air to fuel ratio on one side of the bank, if a tune-up per mileage is coming up, this would be the best place to start
Worn sparkplug will set a lean code, which is caused when the gap of the spark plug exceeds its recommended gap.
