Could be. Wouldn't hurt to spray it out with throttle body cleaner and/or use some Seafoam.

However, if CEL was flashing, that's an ignition system misfire -- something with the plugs/wires/coil, etc. Have the codes scanned by a parts store and see. No need to guess when your computer may tell you exactly what is wrong.
