I just purchased a car 4 days ago and now it's starting to rev up when i'm at a light or idling (sitting in taffic) It doesn't do i much but it does it enough for me to notice it. It's drives fine it only accures when i idling. i had the alternator, starter and battery tested and it came back fine. I had the oil changed and the mechanic said i had a very small oil and transmission leak. I was only enough to make the pan wet. Please help...did i buy a lemon?

Check the idle speed controller and throttle position sensor-also follow link below:
