I have the car WOT in first gear and then the car stalled in 2nd gear, no power

Now the car idle rough, lack a lot of power and I have the ECU code 23 and 31...
It runs so bad that I cannot take a ride without having wide open throttle just to start accelerating
It only accelerate when turbo's boosting and some black smoke is coming out of the exhaust...
The turbine looks good not too much loose, not more than before and it spins freely.
Sound like Piston or ring? Or MAP sensor or MAT sensor?


Celica 1994 with 3SGTE 1995 MR2 (REV 3)

What is these code and what could cause the 3SGTE to run so rough...

There is a list of all the codes and what they mean for each gen engine.
It looks like you have a problem with your map sensor.

that makes sense, if your map sensor took a dump, that would cause all the syptoms u are describing.
