im not sure what you mean by "miss"...you mean misfire? are you sure you are describing the symptom correctly? you described rough idle and what i assume is having to keep giving it gas at idle in order to keep it from stalling. i dont think that is a "miss". i dont think the hose is your problem. i think letting the car sit was the problem and youve got some dirty injectors. put whatever bottle of fuel injector cleaner in there, fill it up, get the engine up to temp and rev it a bit for 50 miles or so. i bet it clears up - especially since the car was running fine before you stopped driving it for a period of time

putting the hose back on should correct whatever symptom that was created by having it off. but again, i dont think thats your problem, especially since you indicate you put the hose back on
