CEL Again. Help please P0170
P0170 Fuel Trim Malfunction(Bank 1) We ran the code in the computer and it gave a list of things it could be. It does start rough sometimes so I dont know if that could be a clue to the problem. Last fall when it was put away it threw another code which was Fuel Pressure Solenoid. I dont remember the number of the code but that could be a contribution to the problem. It runs fine its just that it starts rough sometimes. Where do we start for this one?

the service manual lists these as the possible causes to that code
Volume air flow sensor output frequency
Injector
Fuel pressure
Intake air leaks
Engine coolant temperature sensor
Intake air temperature sensor
Barometric pressure sensor
o2 sensor
Exhaust manifold cracks
