In the old CCC system (pre ODB-II) GM code 42 is EST (Electronic Spark Timing) fault. The HEI module in the distributor could be bad, or there could be a wiring or computer problem. When setting timing on these older cars, you disconnect the four wire connector to the distributor. Did you hook it back up? Is the code active or stored? Try resseting the computer.
