RSX TYPE-S PROBLEMS *Pleas help*

[chaseamundo]

I have an 02' RSX TYPE-S

Recently while driving i noticd my car was having a loss of power so i thought, ok it should go away. so later that day while driving my car just lost all power backfired three times then stalled out while moving. so i pulled over started her up and the check engine light was on, so i went and ran the diagnostic thing through the ECU and it said the map sensor was bad.so on the way to order the sensor she would stall out if i let it idle and would not go over 3k RPMS. it was like it was redlining at 3k.

So i went and ordered the map sensor, put it in and worked for five minutes then the loss of power started again. so i ran another diagnostic on it and it threw another code that it could be an O2 sensor.

i also just notced its spitting out some nasty blackish smoke...maybe from low octane fuel?

ANY IDEAS OF WHAT CAN BE GOING ON?
