I HAVE BEEN GETTING AN ENGINE CODE THE PAST COUPLE OF DAYS, AND I WAS WONDERING IF THERE IS A WAY TO JUMP/BRIDGE THE ALDL TO FLASH THE CODE TO ME. IF ANYONE HAS ANY ANSWERS I WOULD APPRECIATE IT GREATLY

Turn the igniton on (do not start the engine) and insert a paper clip into the two terminals on the top right of the ALDL connector. It should flash a code twelve (no distributor pulse reference) three times then the trouble code 3 times followed by the code 12 3 times. It will keep doing this until you take out paper clip. The trouble codes are listed in the technical articles under Fbody FAQ.

Just in case...

'12' is one flash, a pause, and 2 flashes of the check engine light. It does that 3 times before it will display the codes, and they are read the same way.
