I read your other posts about the ignition control module failure so this new problem may be related or a new one as far as the check engine and anti-theft light turning on. Emissions light? Where?

If the check engine light flashes, it indicates damage may result to your converter if you continue driving. Some members lose their converters in as little as 10 miles. The factory anti-theft system, if I'm not mistaken, will flash its security light if a theft attempt is made (no engine run possible because the fuel pump's disabled) but light up if there's a fault in the system to alert you that its disabled leaving the car without protection. The security light going on and off may light up the check engine light. Same problem but only one can be read by Autozone when the SES light remains on.

Is the random misfiring from the ignition control module problem or an assumption of continuing problems?

BTW, update your info as the L300 has the 3.0L V6 engine while yours is the L200 2.2L 4-cyl. engine. The BCM causes other problems as the car acts "possessed" with lights, horn, and wipers going at random. Check past threads about expensive BCM replacements. Only Saturn can program replacements.

REWARD EXCELLENCE!
