So I'm going to change the spark plugs, and test the coil packs this upcoming friday/saturday to see if that helps. Common sense and past experience with coil pack issues tells me that if one were actually bad, the car would only be running on 3 cylinders and either be hard to start or run very poorly so I'm already expecting the coils to test good since my car is running pretty well.
I've been researching similar issues on this website and from what I've read it could be gas issues or possibly a vacuum leak. Maybe today or tomorrow I'll take off the engine cover and try to spray some carb cleaner and detect any changes in idle for a leak.
If anyone could give me ideas to check that would be awesome as I'm new in the sentra world and could really use some help.
