poor idle and stalling!

I have a 1987 chevy s10 blazer that has very poor idle and occasionally stalls when stopes obd1 is telling me I have a bad map sensor and o2 sensor but so replaced both with no progress! is there something that would make both these pop codes? the fuel pressure is fine brand new alternator, distributer, cap, module, and rotor any help would be amazing!

Have you actually check the fuel pressure with a gauge? whats its reading? I remember when my pump was weak it was showing a map code. if its find,have you tried cleaning your Iac valve? is yours carbed or efi?
