Default 1991 Olds Cutlass Ciera 3.3L

Hello everyone,I have a 91 Olds Ciera FWD 3.3L that is stalling,intermittent misfire off idle,stumbles after warm up, and at times runs fine. Have already replaced crank/cam sensor,ignition module,replaced fuel pump in tank, checked oxygen sensor function it has good cross count,new throttle position sensor.
Fuel pressure running pressure is 40psi. Fuel injectors are working fine electronically.Cleaned MAF sensor hot wires. What am I missing? Anyone with
an tips on these symptoms would be greatly appreciated.
