Help Please!!!!!!!!

I HAVE A 1999 NISSAN SENTRA WITH 80,000 MILES. I RECENTLY GAVE IT A FULL TUNE-UP AND CHANGED THE DISTRIBUTOR. I ALSO BOUGHT A BRAND NEW BATTERY ALL WITHIN 3 MONTHS. EVERY NOW AND THEN MY CAR IS GIVING ME ROUGH STARTS. WHEN I TURN THE KEY IT WILL REV LIKE 4 OR FIVE TIMES THEN KICK OVER AND START. SOMETIMES IT WILL PUTTER A LITTLE, THEN START. DO YOU GUYS HAVE ANY IDEA WHAT IT MY BE. ALSO, THEY DO USE NGK SPARK PLUGS FOR THE TUNE-UP. THIS PROBLEM IS NOT PERSISTENT. IT IS EVERY NOW AND THEN. DO YOU THINK IT COULD BE THE STARTER. SOMEONE CHECKED TO SEE IF MY ALTERNATOR IS CHARGING PROPERLY AND IT IS! THANKS IN ADVANCE GUYS!

not your starter. it does nothing after your car is running. id say get your compression checked and fuel pressure checked.
