('07 LT, 90K miles.)
p1174: "Fuel Trim Cylinder Balance ", per AllData

This code occurs quite regularly. AFAICT, the car has no 'performance issues'. Alldata and others list a number of possible causes, so I don't think I need to see those again.

If anyone has actually fixed this code, what did you do?
In particular, has the fix been cleaning or replacing the injectors?
