How many miles on it? When was the last time you did a fluid/filter change? (should be done around every 40k, just a simple fluid and filter change may fix you up)... Have you thrown any codes? For giggles, take it to autozone and have them pull any codes on there (it's free) Just because the SES light isnt on, doesn't mean that there aren't any stored...
