If you got trouble codes for those sensors, what were the actual codes. Yes, I can look it up, but, if more than one code for one sensor, then, I don't know which code? Before I replace a sensor I try to check the connector wiring circuits, probably ref voltage--ground and signal for that sensor. I can't go by what somebody else did or said. All I can do is make suggestions on what to check, you have to do the testing.
After a vehicle warms up, it's not unusual for the rpms to drop a little.
You say it dies frequently, does it die at idle or going down the highway? If at idle, check and clean the idle air system.
Check cylinder compression, I haven't looked at your compression specs, but usually the minimum is around 100 psi. It may run with less than that, but, with poor compression, it may not run correctly.
