could be a number of things. The first thing i would do is check when the last time you had an engine tune up. Usually every 80000kms is recommended in a sentra. It most likely is the spark gap on your spark plugs, they could be getting old and need to be replaced. I recommend NKG spark plugs, you dont need platinum tipped ones, i find they cause more problems. I hope this helped.
replace the starter

You need to warm the car up with hot water.
same thing started happening on my '97, you will probably need to have a new clutch cable installed. when they get old, sometimes they will start to fray which causes them to stretch and causes your pedal to become sticky.
1989 Nissan Sentra Wagon 5 Speed intermittently wants to die out. Unless I give it gas it will stall. It will start back up again, with the same problem until problem stops. No pattern to diagnose.
Buy 4 qts but start with 3 qts when refilling.
