do a stall test, like start engine let it run then hold the brake pedal with your other foot raise rpm to put load on engine if you feel the hesitate then it could be spark plugs wire or injectors

running rough, could be a few possible things besides spark plugs, and wires! air filter, fuel filter, fuel injectors, fuel pump, coil pack, Etc. Id start with the air and fuel filters! Good luck, Hope this helps!
You seems to be right in judging the fault as it seems that the fuel system is faulty while the car is in an inclination.
So start from your tank, the fuel pump, the filter , the delivery and spark plugs.
Have the entire system cleaned up, do the much needed service for the mileage done..
