Engine Performance problem
2004 Nissan Altima 6 cyl Front Wheel Drive Automatic 85000 miles
My car has been having a rough idle when in a full stop for the past month or two. I originally thought that it may have to do with an old battery. Yet my father-in-law put another batter that could hold charge and it still has that idle.
The only other thing I believe it could be is that the fuel injectors need to be cleaned.
Do you have any ideas for what it could possibly be?
