Having issues

[frosty579]

ok so ive been having problems with ever few times i drive my car if i try to accelerate to fast the rpms stay where there at and it just maintains speed. (makes a sound like its sputering a bit) after many parts and a headach i decided to short out the obd1 port to see what the deal was and i seem to be getting a code not listed. it does the normal 12, 12 but then it goes to 3 fast flashes ( so 03? not listed) it repeats the 3 fast flashes a total of six times before restarting the cycle with 12,12. im completely lost and unfortanitly the military dosent pay enough for me to keep throwing random parts at it or take it in. so if possible i would like to know if im reading the OBD1 wrong. and id also like some more opinions as to what my issues may be. (ive changed fuel filer, throtle possision senser, IAC valve, fuel regulator and cleaned the throttlebody/ intake manifold.)

i would greatly appreciate and help that can be given.
