If the Check Engine Light consistently comes on for 2 seconds and then goes out, when the ignition switch is turned to ON (Position II), then focus on the distributor. Normally, replacing the Ignition Control Module (ICM) and coil in the distributor solves the problem. Be sure to apply silicone heat transfer compound to the back of the new ICM, otherwise it won't last long.
