Have you checked to see what code is flashing? If you do not own a OBD2 Scanner, then stop my Auto Zone and get it read for free, when it comes on. If it is flashing, I'm willing to bet you have a misfire. Start with the plugs and wires.

Correct. I didn't know the engine light would never hold steady. Or if it was pulsing constantly. Sounds like you have a sign of a mis-fire. Start with the basics.
