I would check the codes and no this is NOT a normal condition. if it really runs poorly when the tank shows 1/4, then make sure that your gauge is reading correctly and make sure that you have at least 10 gallons of gas until you precisely find the actual root of this problem

Did you find out what was causing the rough idle? Ha the check engine light come on? Are there any vacuum leaks?
