4 PCM codes. Please help! Thanks

Alright, got 4 codes in my pcm. Following codes: 96 Z28

1351 (think it was random misfire) But this is major!
1441 (Auxilary Emissions for MAP sensor I think)
1641 (same as 1441 I think)
1642 (" ")

Well. Got a new opti, new MAP sensor, new ignition control module, new MSD coil, new wireset, new fuel pump, fuel pressure regulator and a fuel pressure guage. Dont know what is causing this mis unless the damn opti went out that fast. I got some new injectors but tuning so I can run them but cant tune til I fix the misfire. Also new NGKTR55IX plugs, gapped @ 35. Got all that stuff on here and its really bad in first gear and @ 60-100mph. cant get it over 110 mph. If anyone knows what these codes are and what to look for or how to fix this prob, please help. Thanks for any input!
