Yes the engine light is on, stay's on and once in awhile flashes. -
Answer 2
You probably have a misfire condition due to a faulty spark plug or spark plug coil. Need to get code read and post result here to further assist. Autozone provides this for free. -

I got the same problem with my 98 Seville with 67k original. Thought maybe I got some bad gas. The idle skips at stoplight and the takeoff from light seems to be sluggish. No code coming up. -
