Is P0174 the only error or do you get a P0171 too? Do you have headers? I think P0174 is only one bank. Find out which side of the motor and check for exhaust leaks and your coils and plugs. Swap coils on one half of the motor to the other half to see if the error changes banks. If it does, one of your coils is bad. A smoke test is something else to try.
